A small block of mass m, which weighs 7.154 N, is hit so that it slides up a frictionless inclined plane. The surface of the inclined plane is at an angle 0 relative to the horizontal. Just after the
mass is hit it has a speed of 12.80 m/s. The mass slides up the incline and travels a distance D along the incline before starting to slide back down. Find the work done by gravity on the block
from its starting position up the ramp over the distance D. (Use g = 9.80 m/s?.)
