A block of mass M = 4.000 kg is released from rest at the top of an incline of angle θ = 24.0º w.r.t. the horizontal. The coefficient of kinetic friction between the block and the incline is µk = 0.200 and the length of the incline (hypothenuse of the triangle shown below) is L = 6.00 m. ( w.r.t. = with respect to)
I am trying to find:
a. The work done by the normal force for the complete trip down the incline.
b. The work done by friction for the complete trip down the incline.
c. The total work performed by all the forces acting on the block for the trip down.
d. How fast will the block be moving when it reaches the bottom of the incline.
Thanks :)
