A person running at 2 m/s accelerates with a rate of 0.5 m/s2 in 3 s. This is the final velocity of the runner.
What is 3.5 m/s?
400
This resists the initiation of sliding motion between two surfaces that are in contact and at rest.
What is Static Friction?
400
This is the kinetic energy of a 5 kg toy car travelling at 4m/s.
What is 40 J?
400
These are needed to have a change in momentum and are a part of impulse.
What is Force and Time?
500
This is the conversion for 2 km/min to m/s.

A ball is hit straight up with a velocity of 20 m/s, how long will it take for the velocity to reach 0 m/s? (hint a = -9.8 m/s2)
What is 2.02 s?
500
This is the quantity that represents this dependence of friction on the characteristics of the surfaces involved.
What is the coefficient of friction?
500
The top of the first hill of a roller coaster is 95 m above the ground. This is how quickly is the roller coaster cart travelling when it reaches the bottom of the first hill.
What is 43.15 m/s?
500
A 0.5 kg cue ball is struck and rolls towards a stationary 0.5 kg eight ball with a velocity of 5.0 m/s. After they hit the cue ball comes to rest. This is the final velocity of the eight ball.
Rework:
