E A scientist tried to launch an experimental rocket in vertical direction. The tracking device of the rocket shows the flight height is at 83.4 ft when its power shut down. The failure of the parachute to deploy makes the rocket fell freely to the ground after 15 seconds. Determine: (a) the velocity of the rocket when the powered flight shutdown (b) the maximum height reached by the rocket.

E A scientist tried to launch an
experimental rocket in vertical direction. The
tracking device of the rocket shows the flight
height is at 83.4 ft when its power shut
down. The failure of the parachute to deploy
makes the rocket fell freely to the ground
after 15 seconds. Determine: (a) the velocity
of the rocket when the powered flight
shutdown (b) the maximum height reached
by the rocket.
