The change in momentum for an object is equal to
Answer:
We conclude that the change in momentum of a body is equal to the impulse experienced by a body.
Explanation:
Considering the equation
F • t = m • Δ v
Here,
m • Δ v is basically a change in momentum of a body which is equal to the mass of the object multiplied by the change in its velocity.
Also,
F • t is called the impulse of the object.In the formula, it is clear that the impulse experienced by a body during the collision is basically a change in the momentum of the body.
In other words, the change in momentum of a body is equal to the impulse experienced by a body.
Therefore, we conclude that the change in momentum of a body is equal to the impulse experienced by a body.

The middle-C hammer of a piano hits two strings, producing beats of 1.60 Hz. One of the strings is turned to 250.00 Hz. What frequencies (in Hz) could the other string have? (Answer to the nearest 0.1 Hz.)
Answer:
248.5Hz or 251.5Hz
Explanation:
Given :
Beat frequency, Fbeat = 1.5 Hz
Frequency of string 1, f1 = 250 Hz
Frequency of string 2, f2 =?
Recall:
Fbeat = |f1 - f2|
1.5 = 250 - f2
f2 = 250 - 1.5
f2 = 248.5 Hz
OR
- Fbeat = |f1 - f2|
- 1.5 = 250 - f2
f2 = 250 + 1.5
f2 = 251.5 Hz
Hence, the two possible frequencies of the other string are 248.5Hz or 251.5Hz

An oil tank has a base of area 2.5 m2 and is filled with oil to a depth of 1.2 m. The density of the
oil is 800 kg/m3. What is the force exerted on the base of the tank due to the oil?
A. 960N
B. 2400N
C. 9600N
D. 24 000N
Answer:
D. F = 24000[N]
Explanation:
To be able to calculate the force we must first find the pressure at the bottom of the tank. By means of the following equation:
[tex]P=Ro*g*h[/tex]
where:
Ro = density of the liquid = 800 [kg/m³]
g = gravity acceleration = 9.81 [m/s²]
h = elevation = 1.2 [m]
[tex]P=800*9.81*1.2\\P=9417.6[Pa][/tex]
Pressure is defined as the relationship between Force on the area.
[tex]P=F/A\\F=9417.6*2.5\\F = 23544 [N] = 24000[N][/tex]

A 10 kilogram radio controlled airplane at 1000 meters has 100,000
joules of potential energy, and moving at 10 meters per second it has 500
joules of kinetic energy. How much mechanical energy does the radio
controlled airplane have? Include units in your answer but no decimal
point or digits to the right of the decimal point. *
Answer:
The mechanical energy of the airplane is 100,500 joules
Explanation:
The given parameters are;
The mass of the airplane = 10 kg
The height at which the airplane is located = 1000 meters
The potential energy of the airplane, P.E. = 100,000 joules
The speed of the airplane = 10 m/s
The kinetic energy of the airplane, K.E. = 500 joules
The Mechanical Energy, M.E. = The Potential Energy, P.E. + The Kinetic Energy, K.E.
M.E. = P.E. + K.E.
∴ M.E. = 100,000 joules + 500 joules = 100,500 joules
The mechanical energy of the airplane, M.E. = 100,500 joules.

Bu lasarati pushes the trycicle with a force of 20 N so that it moves 10m in the direction of the force. The effort made by Mrs. Lasarati amounts to...
Answer:
200 J
Explanation:
Given that,
Force, F = 20 N
Distance covered in the direction of force, d = 10 m
We need to find the effort made by Mrs. Lasarati. It will be given by :
W = Fd
W = 20 N × 10 m
W = 200 J
So, the required effort made by Mrs. Lasarati is 200 J.
A race car is accelerating at 5m/s and then speeds up to a final velocity of 12 m/s if the race car driver finished this let of the race in 6 seconds what was the car's acceleration
Answer:
the acceleration of the car is 1.167 m/s²
Explanation:
Given;
initial velocity of the race car, u = 5 m/s
final velocity of the race car, v = 12 m/s
time to finish the race, t = 6 s
The acceleration of the car is calculated as;
a = (v - u) / t
a = (12 - 5) / (6)
a = 1.167 m/s²
Therefore, the acceleration of the car is 1.167 m/s²
Answer:
1.167 m/s^2
Explanation:
Given that a race car is accelerating at 5m/s and then speeds up to a final velocity of 12 m/s if the race car driver finished this let of the race in 6 seconds what was the car's acceleration ?
From the question, the following parameters are given
Initial velocity U = 5 m/s
Final velocity V = 12 m/s
Time t = 6 s
According to the definition of acceleration:
Acceleration = change in velocity per time taken.
I.e
Acceleration =( V - U)/ t
Acceleration =( 12 - 5 )/6
Acceleration = 7/6
Acceleration = 1.167 m/s^2
Therefore, acceleration is 1.167 m/s^2
Daniel steps on the gas pedal of his car, and the engine increases its performance from zero to
2700 rpms (rotations per minute). What are the frequency and period?
(Hint: frequency is cycles per second.]
Answer
The frequency and the period are 45 cycles/second and 0.023 seconds
Explanation:
The frequency of the engine is given by :
[tex]f=\dfrac{rpm}{60}[/tex]
We have, the engine increases its performance from zero to 2700 rpms.
Frequency,
[tex]f=\dfrac{2700}{60}\ \text{cycles per second}\\\\f=45\ \text{cycles per second}[/tex]
The time period of the engine is given by :
T = f/f
So,
[tex]T=\dfrac{1}{45}\ s\\\\T=0.023\ s[/tex]
Hence, the required frequency and the period are 45 cycles/second and 0.023 seconds respectively.

Your 1500kg car is stuck behind a truck traveling 27 m/s. To pass it, you speed up to 34 m/s in
6.0 s. What power is required to do this?
Answer:
P = 53375[W]
Explanation:
First, we must use the following equation of kinematics, which allows us to calculate the acceleration value.
[tex]v_{f}=v_{o}+a*t[/tex]
where:
Vf = final velocity = 34 [m/s]
Vo = initial velocity = 27 [m/s]
a = acceleration [m/s²]
t = time = 6 [s]
Now replacing:
[tex]34=27+a*6\\a=1.167[m/s^{2} ][/tex]
Now we must use Newton's second law, which tells us that the sum of forces is equal to the product of mass by acceleration. In this way, we have the following equation.
ΣF =m*a
where:
F = force [N]
m = mass = 1500 [kg]
a = acceleration = 1.167 [m/s²]
[tex]F=1500*1.167\\F=1750[N][/tex]
Power is defined as the product of force by speed. But we have two speeds, the initial and the final. We must use the average speed to be able to estimate the power needed.
[tex]V_{average}=\frac{34+27}{2} =30.5[m/s][/tex]
And the power:
[tex]P=F*V_{average}\\P=1750*30.5\\P=53375[W][/tex]
A force of 2.0 × 102 newtons is applied to a lever to lift a crate. If the mechanical advantage of the lever is 3.43, what is the weight of the crate? A. 2.0 × 102 newtons B. 58 newtons C. 6.9 × 102 newtons D. 7.1 × 102 newtons
Answer:
C. [tex]6.9\times 10^2\ \text{N}[/tex]
Explanation:
[tex]\text{Supplied force}=2\times 10^2\ \text{N}[/tex]
M = Mechanical advantage = 3.43
Mechanical advantage is given by
[tex]M=\dfrac{\text{Weigh of crate}}{\text{Supplied force}}\\\Rightarrow \text{Weigh of crate}=M\times \text{Supplied force}\\\Rightarrow \text{Weigh of crate}=3.43\times 2\times 10^{2}\\\Rightarrow \text{Weigh of crate}=6.86\times 10^2\ \text{N}\approx 6.9\times 10^2\ \text{N}[/tex]
The weight of the crate is [tex]6.9\times 10^2\ \text{N}[/tex].
