What is the weight of a 82.1 kg object on Jupiter, where the acceleration due to gravity is 24.5 m/s2?
Answers
What is the mass of an object that requires 100N of force in order to accelerate 10m/s2
Answers
Explanation:
Hey there!
Given;
Force (f) = 100 N
Acceleration (a) = 10m/s^2.
Mass (m)=?
We have;
Force = mass * acceleration.
So,
100 = m * 10
Or, 100 = 10m
Or, m= 100/10
Therefore, mass is 10kg.

Billiard ball A (0.35 kg) is struck such that it moves at 10 m/s toward a second identical ball (Ball B) initially at rest. After the collision, Ball A continues to move in the same direction at 2 m/s. What is the magnitude of the velocity for Ball B after the collision?
Answers
Answer:
Explanation:
We shall apply law of conservation of momentum during the collision of ball A and B .
Total momentum before collision of A and B = .35 x 10 = 3.5 kg m/s
Let the velocity of B after collision be v .
Total momentum after collision = .35 x 2 + .35v
According to law of conservation of momentum
.35 x 2 + .35v = 3.5
.35 v = 2.8
v = 8 m /s .
The direction of B will be same as direction of A .

1. Deshaun Watson (100 kg) accelerates from rest to 9.0 m/s in 1.5 s. What is the average power
output of Deshaun in kW? (2 mark)
Answers
Answer:
P = 5400[W]
Explanation:
We must use the following equation of kinematics to calculate the acceleration.
[tex]v_{f}=v_{o}+a*t[/tex]
where:
Vf = final velocity = 9 [m/s]
Vo = initial velocity = 0 (starting from rest)
a = acceleration [m/s²]
t = time = 1.5 [s]
[tex]9=0+a*1.5\\a=9/1.5\\a=6[m/s^{2} ][/tex]
Now with this second equation of kinematics, we can determine the distance traveled.
[tex]v_{f}^{2}=v_{o}^{2}+2*a*x[/tex]
where:
x= distance [m]
[tex]9^{2} = 0 +2*6*x\\12*x=81\\x=6.75[m][/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.
∑F = m*a
Now replacing:
[tex]F=100*6\\F=600[N][/tex]
Ahora la potencia se puede calcular por medio del producto de la fuerza por velocidad.
[tex]P=F*v[/tex]
where:
P = power [W]
F = force = 600 [N]
v = velocity = 9 [m/s]
[tex]P=9*600\\P=5400[W][/tex]

When is the net force on the car closest to 0?
Answers
Answer: The net force is the vector sum of all the forces acting on an object. When an object is in equilibrium (either at rest or moving with constant velocity), the net force acting on it zero. A vector can only have zero magnitude if all of its components are zero. there is more than one force acting on an object, then F is the net force. If two people pull on an object with equal forces in opposite directions, then the net force is zero and the acceleration is zero
