Question
Playing shortstop, you pick up a ground ball and throw it tosecond base. The ball is thrown horizontally, with a speed of 24m/s, directly toward a point A. When the ball reaches the secondbaseman 0.50 seconds later, it is caught at point B. (Neglect airresistance.) (a)How far were you from the secondbaseman? Meters. (b)What is the distance of the vertical drop,AB? Meters. Playing shortstop, you pick up a ground ball and throw it tosecond base.

Explanation / Answer
a. Horizontaldistance x = vx* t = 24 *0.5 = 12 m b. h = uy* t + (1/2) * g * t2 h = 0* 0.5 + 0.5 * 9.8 *0.52 = 1.225 m h = 0* 0.5 + 0.5 * 9.8 *0.52 = 1.225 m
