A 200 lb block resting on a horizontal plane.
Determine the magnitude of the force P that is required to give the
block an acceleration of 10 feet / s2 to the right. The coefficient
of kinetic friction between the block and the plane is π
0.30.

equilibrium of forces
ma = F cos x - u ( mg + F sin x)
(200 / 32.2) * 10 = F cos 30 - 0.3* (200 + F sin 30)
62.11 = F cos 30 - 60 - 0.15 F
F = 170.54 lb
