Inclined Planes Problems

Some dynamics SAT Physics exam questions require knowledge of inclined planes.

1. A block of mass m slides down an inclined plane with a constant speed, v. A force F is applied to the block and friction between the plane and the block is negligible. What is the correct orientation of the force F?

2. A block of mass m = 5kg slides down the inclined plane from the figure below. If the coefficient of dynamic friction is .5, what is the acceleration of the block?

a) .115m/s2
b) .15m/s2
c) .25m/s2
d) .475m/s2
e) .67m/s2
