Question: A cat is running at 8.0 m/s and trying to catch a mouse, who has a tenth of the mass of the cat. If the cat speeds up by 2.0 m/s, the cat has ten times of the kinetic energy of the mouse.
Question 1: What is the speed of the mouse?
answer: ______ m/s.
Please show all work and each step to obtain the speed of the mouse.
