What is the rockets initial mechanical energy

Reference no: EM13657086

A 9960 lb rocket is launched straight up, starting at rest. The thrust force pushing the rocket upward is 20000 lb. Air resistance exerts a force of 4000 lb (assumed constant). Think the point at which the rocket is 5.0 miles up.

1. What work does air resistance do?

2. What work does the thrust do?

3. What is the rocket’s speed when it is 5.0 mile sup?

4. What is the rocket’s initial mechanical energy (at launch)?

5. What is the rocket’s final mechanical energy (when it is 5.0 miles up)?
