Solve the all parts of following question:
Question: A father racing his son has 3/5 the kinetic energy of the son, who has 2/5 the mass of the father. The father speeds up by 2.5 m/s and then has the same kinetic energy as the son.
Part A: What is the original speed of the father?
m/s
Part B: What is the original speed of the son?
Please show all work and steps to determine the original speed of the father.
