An object is thrown vertically upward with initial velocity v(0)=20ft/s. Assume that gravitation is the only force acting on the object (gravitational acceleration g=32ft/s).

(a) Find the velocity function v(t)

(b) If the initial position of the object is s(0)= 50ft, find the position of the function s(t).
