QUESTION:
A rocket is launched vertically upward with an initial velocity of 120 m/s from a platform that is 125m above the ground. Assume that the only force at work is gravity. Determine and graph the velocity and position functions of the rocket for \(t\ \geq\ 0\). Then describe the motion in words.
ANSWER:Solution Step 1 Given that the rocket is launched vertically upward with initial velocity 120m/s from a platform of 125 m above the ground. Let us assume that the only force at work is gravity. We have to find the velocity and position function of the rocket for t 0 and to draw the graph of velocity and position function.
