A car accelerates from rest to 27 m/s in 8 seconds. What is the acceleration of the car?
Answer:
The answer is 3.38 m/s²Explanation:
The acceleration of an object given it's velocity and time taken can be found by using the formula
[tex]a = \frac{v}{t} \\ [/tex]
where
a is the acceleration
v is the velocity
t is the time
From the question
v = 27 m/s
t = 8 s
We have
[tex]a = \frac{27}{8} \\ = 3.375[/tex]
We have the final answer as
3.38 m/s²Hope this helps you

Your car burns gasoline as you drive up a mountain road. What energy transformation is taking place?
Answer:
the chemical energy of the gasoline is converted into kinetic energy of the car.
Explanation:
Gasoline contains several chemicals like lubricants, anti-rust agents and anti-icing agents which are added to improve the performance of a car. The energy change taking place during the burning of gasoline is chemical energy to thermal energy.
What is gasoline?Gasoline is a pale brown or pink liquid which is made from the processed crude oil. It evaporates easily and is highly flammable and form explosive mixtures in air. It is a mixture of many hydrogen and carbon containing chemicals which are hydrocarbons.
A typical gasoline mixture contains about 150 different hydrocarbons, including butane, pentane, isopentane and the BTEX compounds like benzene, ethylbenzene, toluene and xylenes.
When a gasoline burns the chemical energy is converted into thermal energy and then this thermal energy is converted into mechanical energy. Gasoline burns and produce heat and this heat is converted into mechanical energy to move the car.

An evacuated long tube contains a coin and a feather. If both objects fall together starting from the top of the tube, it is expected that: If this experiment is repeated at a place 2000 kilometers above the sea-level, the acceleration due to gravity gexp is expected to :
Answer:
gexp = 3.65 m/s²
Explanation:
The value of acceleration due to gravity changes with the altitude. The following formula gives the value of acceleration due to gravity at some altitude from the sea level:
gexp = g(1 - 2h/Re)
where,
gexp = expected value of g at altitude = ?
g = acceleration due to gravity at sea level = 9.8 m/s²
h = altitude = 2000 km = 2 x 10⁶ m
Re = Radius of Earth = 6.37 x 10⁶ m
Therefore,
gexp = (9.8 m/s²)(1 - 2*2 x 10⁶ m/6.37 x 10⁶ m)
gexp = 3.65 m/s²

Two brifks that weight 20 lbs fall off a building. Brick A falls from 30 feet
and Brick B falls from 10 feet. Which brick has more energy? *
Answer:
Brick A has more energy because its weight is more, that means that the gravitational pull to the earth will be more if the brick will fall from 30 feet.

A baseball traveling at a velocity of 35 m/s has a mass of
0.15 kg. What is the kinetic energy of the baseball?
Answer:
35 m/s = v KE= 1/2 m x v^2. 89= m x 1224
89 J = KE 89 = 1/2 (m) x (35)^2. m = 0.15 kg.
What would the gravitational field strength be on a planet with twice Earth's mass
and twice its radius?
78.4 N/kg
39.2 N/kg
19.6 N/kg
9.8 N/kg
4.9 N/kg
Answer:
a = G M / R^2 acceleration due to gravity
aE /aP = (ME / RE^2) / (MP / RP^2) = (ME / MP) * (RP^2 / RE^2)
Since MP = 2 ME and RP = 2 RE
aE / aP = 1/2 * 2^2 = 2
So the gravitational field strength of the planet is 1/2 that of the earth or 4.9 N/kg

2. A girl throws a marshmallow that lands in her friend's mouth 2 m away. The girl threw the marshmalow
at an angle of 30 degrees. How hard did she throw the marshmallow?
Answer:
The speed at which she threw the marshmallow is approximately 4.76 m/s
Explanation:
The given in formation are;
The range in which the marshmallow was thrown = 2 m (The location of her friend)
The angle at which the marshmallow was thrown = 30 degrees
The horizontal range is given by the following formula;
[tex]R = \dfrac{u^2 \times sin(2\cdot \theta)}{g}[/tex]
Where;
R = The range = 3 m
u = The initial velocity
θ = The angle at which the marshmallow was thrown = 30°
g = The acceleration due to gravity = 9.81 m/s²
By substitution, we have;
[tex]2 = \dfrac{u^2 \times sin(2\times 30)}{9.81} = \dfrac{u^2 \times sin(60)}{9.81}[/tex]
[tex]\therefore u^2 = \dfrac{ 2 \times 9.81}{sin(60)} = \dfrac{u^2 \times sin(60)}{9.81} \approx 22.66[/tex]
u ≈ √(22.66) ≈ 4.76 m/s
u ≈ 4.76 m/s
The speed at which she threw the marshmallow ≈ 4.76 m/s.
Answer:
4.76 m/s

A ferry is crossing a river. The ferry is
headed due north with a speed of 2.6 m/s
relative to the water and the river’s velocity
is 4.4 m/s to the east.
a) What is magnitude of the boat’s velocity relative to Earth?
Answer in units of m/s
b) Find the direction in which the ferry is
moving (measured from due east, with counterclockwise positive).
Answer in units of ◦
.
Answer:
a. 5.1 m/s b. 149.42°
Explanation:
a. Velocity of boat relative to earth, V = velocity of boat relative to river, V'+ velocity of river relative to earth, v.
We add these vectorially.
Since velocity of boat relative to river is 2.6 m/s due north and velocity of river relative to earth is 4.4 m/s due east, we apply Pythagoras' theorem and add them together since both velocities are perpendicular to each other.
So, V² = V'² + v² = (2.6 m/s)² + (4.4 m/s)² = 6.76 (m/s)² + 19.36 (m/s)² = 26.12 (m/s)²
V = √[26.12 (m/s)²]
V = 5.1 m/s
b. Since the relative velocities of the ferry relative to the water and the velocity of the river relative to the earth are the components of the velocity of the ferry relative to the earth, the y - component being the velocity of the ferry relative to the earth since it is due north, and the x- component being the velocity of the river relative to the earth since it is due east. So, we have that
tanФ = y - component/x - component = V'/v where Ф is the angle between V and the west direction.
tanФ = V'/v
tanФ = 2.6 m/s ÷ 4.4 m/s
tanФ = 0.5909
Ф = tan⁻¹(0.5909)
Ф = 30.58°
So, the angle measured from due east with counterclockwise direction positive is 180° - Ф = 180° - 30.58° = 149.42°

On Thursday your best friend calls and invites you to go bowling and to dinner on Saturday. What should you do and Why?
Answer:
No you should not go
Explanation:
Because if you go you will be more behind and then you’ll get so stressed from the work that you didn’t do and then it will just keep on stacking up and get more and more stressed and also another reason is because you should do the responsible choice and stay home and work on your project so you would be telling your friend that you can not go Because you got work to do and maybe you could schedule it for the next weekend and have your fun next week and you should always do the responsible choice.

:: gravitational field force strength
:: mass
Answer: Force
Explanation: Force is defined as a push or pull acting on an object
