Concept clarification: A rocket, initially at rest on the ground, accelerates straight upward from rest with constant (net) acceleration 49.0 m/s. The acceleration period lasts for time 9.00 s until the fuel is exhausted. After that, the rocket is in free fall. Yr.grav Vf.grav Igrav Tthe "free fall" is in the broader sense in which the object is under the sole influence of gravity. Here after the fuel is exhausted, the rocket continues to go upward (becuse it has an upward velocity) till it reaches a maximum height, then it goes downward to the ground. Here we look at the two stages of upward motion as shown in the figure. This is a problem involving multiple steps. In "Hints" the problem is broken into multiple steps, so that you can check each step is correct before moving on to next step.
