A model rocket of mass 0.250kg is launched vertically with an engine that is ignited at time t = 0, as shown. The engine provides an impulse of 20.0 N•s by firing for 2.0s. Upon reaching its maximum height, the rocket deploys a parachute, and then descends vertically to the ground.
(a) On the figures below, draw and label a free-body diagram for the rocket during each of the following intervals.
(b) Determine the magnitude of the average acceleration of the rocket during the 2 s firing of the engine.
(c) What maximum height will the rocket reach?
(d) At what time after t = 0 will the maximum height be reached?
