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.
