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).

A particle with mass m=1 kg is thrown vertically upward in a constant gravitational field with an initial speed of v0=8 m/s. There is a retarding force F = - k m v2 acting on the particle where v is the instantaneous speed and k=1.5 (in SI units). The speed of the particle when it returns to the initial position is
