Q1. A 1500kg car skids to a halt on a wet road where mu_k = 0.54. How fast was the car travelling if it leaves 70 m-long skid marks?

Q2. As a baseball is being caught, its speed goes from 29.50 m/s to 0.0m/s in about 0.00050 s. The mass of the baseball is 0.135kg. What's the acceleration?

Q3. A 65kg trampoline artist jumps vertically upward from the top of a platform that is 2 m above the trampoline with a speed of 4.80m/s.

If the trampoline behaves like a spring of spring constant 6.3×10^4 N/m, how far does he depress it?
