Work problem 38

A student kicks a slipper weighing 80 g to slide on the floor perpendicular to a wall. The slipper is subjected to a constant frictional force of 0.24 N. When it is 1.5 m away from the wall, it has a speed of .

  • What is the kinetic energy of the slipper when it is 1.5 m away from the wall?

  • How much work is done by the frictional force over the 1.5 m distance?

  • At what speed does the slipper collide with the wall?
