Note: Figure not drawn to scale. A model rocket of mass 0.250 kg is launched vertically with an engine that is ignited at time t = 0, as shown above. The engine provides an impulse of 23.5 N.s by firing for 2.0s. Upon reaching its maximum height, the rocket deploys a parachute, and then descends vertically to the ground. On the figures below, draw and label a free-body diagram for the rocket dm mg each of the following intervals. What is the change of momentum during the time the engine is fired? Determine the magnitude of the average acceleration of the rocket during the 2 s firing of the engine. What height will the rocket reach during the period that the engine is fired?
