The graph below shows the velocity v in feet per second of a small rocket that was fired from the top of a tower at time t = 0 (tin seconds). The rocket accelerated with constant upward acceleration until its fuel was expended, then fell back to the ground at the foot of the tower. The entire flight lasted 14 seconds. 4. (4,96) 7(seconds) (14,-224) (a) What was the acceleration of the rocket while its fueled lasted? (b) How long was the rocket rising? (c) What distance did the rocket travel during the time it was rising? (d) How high was the tower from which the rocket was fired? v (ft/sec)
