# A rocket is fired from rest from the ground (y = 0) at time

A rocket is fired from rest from the ground (y = 0) at time.
A rocket is fired from rest from the ground (y = 0) at time t1 = 0 s. As the rocket is burning its fuel, it movesvertically upward with a constant acceleration of 4.25 m/s2. At t2 = 7.50 s, all the fuel has been used up and therocket is in free fall. Air resistance can be neglected up until t4 = 15.0 s when the rocket deploys a parachute. Atthis time the rocket immediately reaches its terminal velocity which means that its acceleration becomes 0 m/s2. a) Find the maximum height of the rocket with respect to the ground. b) How long after being launched does the rocket return to the ground?c) Sketch an ay v. t plot for the motion of the rocket. Be sure to label the accelerations of the rocketat t1=0 s, t2=7.50 s, t3 (when the rocket is at its highest point), t4= 15.0 s, and t5 (when the rocket returns to theground).d)Sketch a vy v. t plot for the motion of the rocket. Be sure to label the velocities of the rocket att1 = 0 s, t2 = 7.50 s, t3 (when the rocket is at its highest point), t4 = 15.0 s, and t5 (when the rocket returns to theground). e)Sketch a y v. t plot for the motion of the rocket. Be sure to label the positions of the rocket att1 = 0 s, t2 = 7.50 s, t3 (when the rocket is at its highest point), t4 = 15.0 s, and t5 (when the rocket returns to theground)
