A car is strapped to a rocket (combined mass = 661 kg), and its kinetic energy is 66,120 J.
At this time, the rocket runs out of fuel and turns off, and the car deploys a parachute to slow down, and the parachute performs 36,733 J of work on the car.
What is the final speed of the car after this work is performed?
Answers: 2
is the initial kinetic energy of the car
