▶2/211 Abatter hits the baseball A with an initial velocity of vo = 30 m/s directly toward fielder B at an angle of 30° to the horizontal; the initial position of the ball is 0.9 m above ground level. Fielder B requires s to judge where the ball should be caught and be- gins moving to that position with constant speed. Because of great experience, fielder B chooses his running speed so that he arrives at the "catch posi- tion" simultaneously with the baseball. The catch position is the field location at which the ball alti tude is 2.1 m. Determine the velocity of the ball rel ative to the fielder at the instant the catch is made Ans. VAB = 21.5i - 14.19j m/ y

The quarterback Q throws the football when the receiver R is in the position shown. The receiver’s velocity is constant at 9.4 yd/sec, and he catches passes when the ball is 8.5 ft above the ground. If the quarterback desires the receiver to catch the ball 3.0 sec after the launch instant shown, determine the initial speed v0 and angle θ required.
In slow pitch softball, the underhand pitch must reach a maximum height of between 1.8 m and 3.7 m above the ground. A pitch is made with an initial velocity vo with a magnitude of 13 m/s at an angle of 33° with the horizontal. Determine (a) if the pitch meets the maximum height requirement, (b) the height of the ball as it reaches the batter.
