Question

A 25-kg solid metal on a 60.0 degree frictionless inclined plane is given a 250-N push upward (parallel to the inclined plane) By how much will the metal accelerate?

Answer 1

force of gravity down slope = 25 *9.81 sin 60 = 245 sin 60 = 212 N
250 - 212 = 37.8 net Newtons upward
37.8 = m a
a = 37.8 / 25
