Q1. A skier is accelerating down a 30.0° hill at a = 4.50 m/s2

(a) what is the vertical component of her acceleration? m/s2 (downward)

(b) How long will it take her to reach the bottom of the hill, assume she starts from rest and accelerates uniformly, if the elevation change is 306 m?

Q2. A 40 percent efficient electric power plant produces 900MW of electric power and discharges waste heat into 30 C ocean water. Suppose the waste heat could be used to heat homes during the winter instead of being discharged into the ocean. A typical American house requires the average 30 kW for heating. How many homes could be heated with the waste heat of this one power plant?
