A stupid man shoots a bullet straight upwards. The bullet leaves the gun at time t = 0 with velocity v = v0 = 200 m/s [U]. Assume a = 9.81 m/s2 [D] and yo = y (t=0) = 0. 2) At what time t > 0 is the velocity of the bullet 10.0 m/s [D]? 3) What is the maximum altitude of the bullet? 1) When is the bullet at an altitude of 500 m
