A boy and his dogs are running. The white dog has a mass of 10 kg. The black dog has a mass of 20 kg. The boy has a mass of 40 kg. They are all running at 3 m/s. 1. Determine the kinetic energy of the dogs and the boy. Record the kenetic energy for each.

2. Suppose the smaller dog (the white dog) speeds up to 6 m/s. What is the kenetic energy of the dog now? How is kenetic energy related to speed?

I need answers quick if possible please!
