QUESTION:
Problem 9PE
Compare the kinetic energy of a 20,000-kg truck moving at 110 km/h with that of an 80.0-kg astronaut in orbit moving at 27,500 km/h.
ANSWER:
Step 1 of 6:
The kinetic energy of a body is the energy possessed due to its motion. We have two situations here. They are the moving truck and the orbital motion of an astronaut. Both are moving with the certain speeds. We are going to compare their kinetic energy.
