Acannonball with mass m is fired with initial speed vinital from a cannon pointed at an angle 8 above the horizontal. compute the time it will take the ball to reach its maximum height, and compute this maximum height, in terms of indial, 8. and g. note that when the ball's height reaches a maximum, its speed in the vertical direction will be zero.

Air at a pressure of 1atm and a temperature of 40 c is in parallel flow over the top surface of a flat plate that is heated to a uniform temperature of 120 c. the plate has a length of 0.40m (in the flow direction) and a width of 0.15m. the reynolds number based on the plate length is 50, 000. what is the rate of heat transfer from the plate to the air? if the free stream velocity of the air is doubled and the pressure is increased to 10 atm what is the rate of heat transfer?
