A 9500-kg test missile blasts off vertically from the ground with a constant upward acceleration
of 2.28 m/s2
. When it has reached a height of 550 m, its engines suddenly fail; the only force
acting on it is now gravity.

b) How much time will elapse after engine failure before the rocket comes crashing down the
ground, 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 a negligible air resistance. When it has reached a height of 525 m, its engines suddenly fail so that the only force acting on it now is gravity. Sketch the x-t graph, v-t graph and a-t graph of the rocket’s motion from the instant of blast-off to the instant just before it strikes the launch pad.

- A 2540 kg test rocket is launched vertically from the launch pad. Its fuel (of negligible mass) provides a thrust force such that its vertical velocity as a function of time is given by v(t) = At + Bt2, where A and B are constants and time is measured from the instant the fuel is ignited.
