Suppose a tennis canon located at ground level fires a ball at a 45 angle to the ground with a speed of 80 feet per second. In calculating the trajectory of the ball you may exclude the effect of air resistance and assume the only force acting on the ball is gravity which accelerates the ball downward at a rate of 32 feet per second.
How high is the ball at its highest point?
a) 20 feet b) 20/2 feet
c) 32 feet d) 50 feet
e) 50/2 feet f) 64 feet
g) 6472 feet
h) 100 feet

Air is to be preheated by hot exhaust gases in a cross-flow heat exchanger before it enters the furnace. air enters the heat exchanger at 95 kpa and 20°c at a rate of 0.6 m^3/s. the combustion gases (cp = 1.10 kj/kg°c) enter at 160°c at a rate of 0.95 kg/s and leave at 95°c. determine the rate of heat transfer to the air and its outlet temperature.
