6. A merry-go-round, having a radius of 2.5 m, is set in motion starting from rest, by students
applying a force of 500 N tangential to the rim of the wheel. After five seconds of torque, the
students let go and measure the rotational speed: 1.25 rad/s. The rotational inertia of the
merry-go-round is:

A crate is being pushed with a constant horizontal force, F. Four forces can be identified:
1) F, 2) the gravitational force, 3) the normal force, and 4) the frictional force. Which forces
do no work on the crate?
