Q1. On an icy day, you worry about parking the car in your driveway that has an incline of 12 degrees. Your neighbour's driveway has an incline of 9.00 degrees, and the driveway across the street is at 6.00 degrees. The coefficient of static friction between tire rubber and ice is 0.15. Which driveway will be safer to park in?

Q2. A 40-kg girl is bouncing on a trampoline. During a certain interval after leaving the surface of the trampoline, kinetic energy decreases to 240J from 470J. How high does she rise during this interval? Avoid air resistance.
