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?

1. study the scenario. the particles in some system are moving around quickly. a few minutes later, the particles are moving, on average, more slowly. how does this change in motion affect the temperature of the system? the temperature of the system did not change. the speed of the particles does not affect temperature, the number of particles affects the temperature. the temperature of the system is lower now than it was initially. faster moving particles result in a higher temperature for the system. the temperature of the system is higher now than it was initially. slower moving particles result in a higher temperature for the system. the temperature of the system did not change. the speed of the particles has no effect on the temperature, only the type of atom affects the temperature.
