8 Energy – forces doing work

Question 13

A spacecraft's return capsule is descending back to Earth. To ensure a safe landing, the capsule is slowed down first by a large parachute and then by firing retro-rockets (which provide an upward thrust) just before it reaches the ground.

Describe the energy changes that occur, in terms of the work done by the forces acting on the capsule, as it descends to a safe stop.
