A dog chasing a cat has 0.53 times the kinetic energy of the cat, and the cat has 0.47 times the weight of the dog. The dog speeds up by 1.24 m/s and then has the same kinetic energy as the cat. What was the original difference in speed of the dog and cat? In other words, what is Veat Udog INitially (before the dog speeds up)? {:Um - dg)i = m/s
