Reference no: EM13491298

You have designed a rocket to be used to sample the localatmosphere for pollution. It is fired vertically with aconstant upward acceleration of 20 m/s2. After 25 seconds, the engine shuts off and the rocket continues rising (infreefall) for a while. (Neglect any effects due to air resistance.)The rockets eventually stops rising and then falls back to theground. You want to get a sample of air that is 20 km above theground.

A. What is the highest point (in km) your rocketreaches? Did you reach your height goal?

B. Determine the total time the rocket is in the air.

C. Find the speed of the rocket just before it hits the ground.
