Two bumper cars in an amusement park ride collide elastically as one approaches the other directly from the rear. Car A has a mass of 435 kg and car B 495 kg, owing to differences in passenger mass. If car A approaches at 4.5 m/ and car B is moving at 3.70 m/s,
(a) What are their velocities after the collision?
(b) and what is the change in momentum of each?
Make an order-of-magnitude estimate of your power output as you climb stairs. In your solution, state the physical quantities you take as data and the values you measure or estimate for them. Do you consider your peak power or your sustainable power?
