Kinetic Energy  Questions II.3.1

 Determine the kinetic energy of a 1200 kg roller coaster car that is moving with a speed of 15 m/s.
 If the car in part a) was moving with three times the speed, what would be its new kinetic energy?
 A 2.0 kg boulder is dropped from a height of 5.0 m. What is the kinetic energy of the boulder as it hits the ground?
 A 12.0 N object has kinetic energy of 275 J. What is the speed of the object?
 How much work must be done to accelerate a 0.20 kg hockey puck from 11 m/s to 17 m/s?
 A 3.0 kg box was lifted vertically and then dropped.
 How much work was required to lift the box 75.0 m?
 If the box was dropped from a height of 75.0 m, what would its kinetic energy be just before it reached the ground?
 What would its velocity be just before it hit the ground?
 A 0.25 kg hockey puck is traveling at 18.0 m/s.
 What is its kinetic energy?
