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?
What is the specific heat capacity of other substance.
