Q1. A Ford Mustang can accelerate from 0 to 60 in a time of 5.4. A Mini Cooper isn't capable of such a rapid start, but it can turn in a very small circle 35 in diameter. How fast would you need to drive the Mini Cooper in this tight circle to match the magnitude of Mustang's acceleration?
Q2. A 53 kg skier skis directly down a frictionless slope angled at 12° to horizontal. Choose the positive direction of the x axis to be downhill along the slope. A wind force with component Fx acts on the skier. What is Fx if the magnitude of the skier's velocity is (a) constant, (b) increasing at the rate of 1.2 m/s2, and (c) increasing at the rate of 2.5 m/s2. Use g=9.81 m/s2.
