Question

A rocket starts from rest and moves up with acceleration 2y. After time t, engine is switched off.
Up to what maximum height from ground does the rocket reach?​

Answer 1

Answer:

Acceleration = resultant force divided by mass = 4.51 ÷ 0.050 = 90 metres per second squared (90 m/s2). This means that, every second, the speed of the rocket increases by 90 m/s. This is nine times the normal acceleration due to gravity. The same method can be used for a full-sized rocket such as the Space Shuttle.
