A 25.0 kg block is pulled 4.5 meters up a 20° rough incline by an applied force Fa = 200 N, directed up the ramp. The block starts from rest and has a final speed of 1.5 m/s.
Find the following:
a) The total work done on the block, Wtot =___ J
b) The work done on the block by friction, Wf =___ J
c) The force of friction, fk =___ N
d) The coefficient of friction, μk =____
