# Kinematics: Speed and Distance

1. An object of mass 1 kg traveling at 5.0 m/s enters a region of ice where the coefficient of kinetic friction is 0.10. Find the distance the object travels before coming to rest.

2. A glider is on a frictionless airtrack that is inclined at 8° with the horizontal. The glider is released from a point 100 cm from a bumper at the bottom of the track, and it rebounds after losing 20% of its kinetic energy during the collision. A) What is the glider's speed just after hitting the bumper? B) How far from the bumper does the glider travel on the rebound (i.e., how far up the incline does it travel)?
