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. using the velocity function, d) using the time at which the rocket returns to 120 feet, find the velocity wheen the rocket returns to 120 feet above the ground. Is the velocity significant? e) what is the velocity when the objects hit the ground
