1. A 10-1b projectile is fired from a catapult with an initinl velocity. Vo = 120 fus at an angle 8 = 35º with the horizontal, and starting position is 7-ft above the ground level. The projectile is fired to a field that is 20-ft above the ground and there is a fench of height 8-ft in top of the ground as shown in Fig. 1. Determine (a) the time duration of the flight, and (b) the maximum height above the horizontal field attained by the ball. [30 Points) 1 Vo = 120 ft/s fence 1 0 = 36 20 120 35' Fig. 1
