1. A 7500 kg rocket blasts off vertically from the launch pad with a constant upward acceleration of 2.25 m/ and feels no appreciable air resistance. When it has reached a height of 525 m, its engines suddenly fail; the only force acting on it is now gravity.

(a) What is the maximum height this rocket will reach above the launch pad?

(b) How much time will elapse after engine failure before the rocket comes crashing down to the launch pad, and how fast will it be moving just before it crashes?

A 7500-kg rocket blasts off vertically from the launch pad with a constant upward acceleration of 2.25 m/s² and feels no appreciable air resistance. When it has reached a height of 525 m, its engines suddenly fail; the only force acting on it is now gravity. (a) What is the maximum height this rocket will reach above the launch pad? (b) How much time will elapse after engine failure before the rocket comes crashing down to the launch pad, and how fast will it be moving just before it crashes?

A rocket blasts off vertically from rest on the launch pad with an upward acceleration of 2.20 {m/s^2}. At 30.0 {ms} after blastoff, the engines suddenly fail, which means that the force they produce instantly stops.

How high above the launch pad will the rocket eventually go?

How long after it was launched will the rocket fall back to the launch pad?

How fast will it be moving when it does so?

A 7700 rocket blasts off vertically from the launch pad with aconstant upward acceleration of 2.35 and feels no appreciable airresistance. When it has reached a height of 550 , its enginessuddenly fail so that the only force acting on it is nowgravity.
