Initially at rest a single-stage rocket is launched vertically from the ground. the rocket’s thrust overcomes gravity and provides the rocket a constant upward acceleration a. the fuel is exhausted 10 seconds after launch and then the motion of the rocket is free fall only due to gravity. if the total flight time is 30 s when the rocket strikes the ground, determine (a) the initial acceleration a, (b) the rocket’s impact speed as it hits the ground, (c) the height h from the ground the rockets reaches
