###### Question:

1. A block of mass m = 5.0 kg is pulled along a horizontal floor or up the ramp by a force of magnitude F = 50 N. The coefficient of kinetic friction between the block and surface is 0.15 and the magnitude of the angle θ = 25.0°.
(a) Make a free-body diagram of the block for each case.
(b) Calculate the magnitude of the normal force and kinetic friction force for each case.
(c) Calculate the acceleration of the block.
