Q1. A 22 kg girl slides down a playground slide that is 8.50 m high. When she reaches the bottom of the slide, her speed is 3.40 m/s.

if the slide is inclined at 20°, what is the coefficient of friction between girl and slide?

Q2. Assume that a 16.5 m/s wind is blowing across the roof of your house. The density of air is 1.29 kg/m3. Conclude the reduction in pressure (below atmospheric pressure of stationary air) that accompanies this wind.
