A 30-kg box slides down an inclined plane of 48 o when pushed downward with a force of 150-N. If the force of
friction is 300-N, find the (a) acceleration of the box and the (b) coefficient of friction between the box and the
plane.
An apple falls from a tree 3.75-m above the ground. Find the (a) time the apple is in the air and (b) its vertical
velocity when it hits the ground.
A softball rolls off the roof of a building that is 7.2-m tall at a horizontal speed of 3.4 m/s. Find the (a) time the
ball is in the air, (b) the final horizontal velocity, (c) the final vertical velocity and (d) the distance it lands away
from the building.
A football is kicked at a 58o angle with an initial velocity of 27.5 m/s. Find its (a) hang time, (b) range and (c)
maximum height.
