A 3.00 kg block is released from rest at the elevated end A of a frictionless track that slopes down to a point B and continues horizontally to a point D, beyond which is a rough horizontal surface (friction). The speed of the block at a point C between B and D is 7.20m/s, and the block comes to rest after sliding 2.77 m along the rough surface.
a) Find the work done on the block by the normal force exerted by the track.
WN = ____________________
b) Find the work done on the block by the gravitational force exerted by the earth.
Wg =_____________________
c) Find the height of A with respect to B.
h = _____________________
d) Find the work done on the block by the frictional force exerted by the rough surfaced
Wf =________________________
e) Find the coefficient of kinetic friction between the block and the rough surface.
