3. The diagram shows a space rocket on its launch pad.

Engine thrust




Resultant upward
force = 10000N




Weight = 200000N

The rocket and fuel have a mass of 20 000kg and weigh 200000N.
It is powered by 3 rocket engines.
At lift-off, the resultant upwards force…

(b) The thrust of the engines remains constant for as long as they are being fired. However,
the acceleration of the rocket continues to increase after lift-off. By referring to the
equation in (a)(ii), explain why the acceleration continues to increase. [3]
