A batter hits the baseball A with an initial velocity of vo = 93 ft/sec directly toward fielder B at an angle of 37° to the horizontal; the initial position of the ball is 1.8 ft above ground level. Fielder B requires 0.34 sec to judge where the ball should be caught and begins moving to that position with constant speed. Because of great experience, fielder B chooses his running speed so that he arrives at the "catch position" simultaneously with the baseball. The catch position is the field location at which the ball altitude is 6.6 ft. Determine the velocity of the ball relative to the fielder at the instant the catch is made. VO 137° 1.8' Answer: VA/B = (i 203' B i+ i j) ft/sec

Q4 2. A ball is launched with an initial velocity of Vo = 4.5 m/s from point P at a 30° sloped surface with an angle of 0. The ball lands at point B, which is 0.6 m higher than point A. Determine the launch angle 0 of the ball, the impact velocity at B (vB), the angle vg makes with the horizontal and the duration of the flight. Also determine the radius of curvature of the path and the rate of change of the speed of the ball at point C, where its trajectory makes an angle of 60° with the negative x-axis. g 9.81 m/s-.

The quarterback Q throws the football when the receiver R is in the position shown. The receiver's velocity is constant at 8.8 yd/sec, and he catches passes when the ball is 7.9 ft above the ground. If the quarterback desires the receiver to catch the ball 3.2 sec after the launch instant shown, determine the initial speed vo and angle e required. 6.0' R 36 yd Answers: Vo = i ft/sec
While scrambling directly toward the sideline at a speed vQ = 18 ft/sec, the football quarterback Q throws a pass toward the stationary receiver R. At what angle α should the quarterback release the ball? The speed of the ball relative to the quarterback is 67 ft/sec. Treat the problem as two-dimensional.
