1) At the Augusta Ice Forum, you notice a 20kg box sitting on the ice at rest. The ice is perfectly frictionless. You push the box in a horizontal direction with 10.0N of force for 5.00m. What is the Kinetic Energy and speed of the box when you are finished pushing?
Correct Answer: No answer given yet a b c d e
2) After you finished pushing the box above it is headed toward an exit gate. There is a small frictionless ice ramp at the gate (someone left a hose on). The box must rise to a height 0.20m above the ice rink floor to reach the top of this ice bump. What is the kinetic energy of the box at the top of this bump?
3) As the box leaves the rink through the exit gate it has a speed of 1.00m/s. It now encounters a level floor with coefficient of friction 0.20 . How far does the box slide out of the gate before coming to rest?
