Q1. A golf ball is struck with a five iron on level ground. It lands 95.3 m away 4.50 s later. What were (a) direction and (b) magnitude of the initial velocity?
Q2. When it rains water vapour in the air condenses into liquid water and energy is released. How much energy is released when 0.0244m of rain falls over an area of 2.59 x 10^6 m^2? If the average energy needed to heat one home for a year is 1.40 x 10^11 J how many homes can be heated with an energy determined in part a?
