A physics book was thrown from the top of a library with a speedof 8.0 m/s at angle 60o with the horizontal. After 5 seconds, thebook hits the ground:
(a) Find the height of the library above the ground.
(b) Find the distance of the point where the book falls on theground from the base of the library.
(c) Just before the book hits the ground, find the horizontaland vertical components of its velocity.
