(4.5.40) A cannon is aimed 35° above the horizontal. (a) The cannon fires towards a 50m-high wall whose base is 150m away from the cannon, measured horizontally. What is the minimum speed at which the cannonball must be fired in order to clear the wall? (Neglect the height of the barrel of the cannon.) (b) On the other side of a cliff is a 30-m high balcony. If the cannonball is fired at the speed you found in part (a), find the horizontal and vertical components of the cannonball's velocity as it strikes the balcony. 50m 30m 150m
