A toy rocket is lauched from the top of a building 120 feet tall at an initial velocity of 200 ft/sec. The position at time t is given by s(t) = -16t2+v0t+s0 and the velocity at time t is given by v(t) = -32t+v0 where v0 is the initial velocity and s0 is the initial height.d) at what time does the rocket return to 120 feete) after how many seconds will it hit the ground
