A race car of mass m is moving with speed v on a straight road. It then accelerates in the direction of its motion at a constant rate a for an amount of time \Delta t
What is the magnitude of the impulse delivered to the car during this time?
m a \Delta t

The graph represents the force exerted by a barrier on a ball as the ball collides with and bounces off the barrier. The initial and final velocities of the ball are the same magnitude, but the opposite direction. How will the graph change if the velocities are twice as large over the same amount of time?
(The peak doubles)

The tendency of an object to resist changes in its motion
What is inertia
300
This is the magnitude of the net force acting on the object.
What is 5 N

This is the angular acceleration of a ball with radius R as it rolls down a ramp without slipping over t seconds, reaching a final speed of v_f
What is:
v_f/(t R)

A cart carrying sand has a hold in the bottom that allows sand to spill out. At time t_1, the cart has speed 1.5 \text{ m/s}. A short time later at time t_2, the cart still has speed 1.5 \text{ m/s} 0.02 \text{ kg} of sand has fallen out of the hole in the cart between t_1 \text{ and } t_2. What is the magnitude of the change in momentum of the cart and its contents between t_1 \text{ and } t_2 \text{?}
0.03 kg m/s
