A boy and his dog are running. The dog has a mass of 20kg and the boy has a mass of 45kg.
Suppose both the dog and the boy run at a speed of 3m/s. Evaluate the expression for kinetic energy to find both of their kinetic energies:
KE of Boy:
KE of Dog:
Suppose the dog speeds up and is now running at a speed of 6m/s. Calculate the dog’s new KE.
New KE of Dog:
