Two gerbils run in place with a linear speed of 0.50 m/s on an exercise wheel that is shaped like a hoop. find the angular momentum of the system if each gerbil has a mass of 0.22 kg and the exercise wheel has a radius of 8 cm and a mass of 4.5 g.

Anonzero net force acts on a particle and does work. which one of the following statements is true? the kinetic energy of the particle changes, but the speed of the particle does not change. the kinetic energy of the particle does not change, but the speed of the particle does change. the kinetic energy of the particle changes, but the velocity of the particle does not change. the kinetic energy and the speed of the particle change, but the velocity of the particle does not change. the kinetic energy, speed, and velocity of the particle change.
