3. A child is trying to throw a ball over a fence. She gives the ball an initial speed of 8.0 m/s at an angle of 40 above the horizontal. The ball leaves her hand 1.0 m above the ground and the fence is 2.0 m high. The ball just clears the fence while still traveling upwards and experiences no significant air resistance. How far is the child from the fence? A. 0.73 m B. 3.8 m C. 2.7 m D. 7.5 m E. 1.6 m 4. A hobbyist launches a projectile from ground level on a horizontal plain. It reaches a maximum height of 72.3 m and lands 111 m from the launch point, with no appreciable air resistance. What was the angle of launch if g = 9.80 m/s? A. 69.0 B. 22.6 C. 67.4 D. 44.8
