Weather rocket generates a thrust problem

Reference no: EM13669392

A 10.2 kg weather rocket generates a thrust of 200N. The rocket, pointing upwards, is clamped to the top of a vertical spring, whose spring constant is 500N/m and is anchored to the ground

1) After the rocket has ignited what is the speed when the spring has stretched 40 cm?

2) Initially before the engine is ignited the sits at rest on top of the spring. How much is the spring compressed?
