Question

A baseball player bats the ball at 60° with the ground at a velocity of 50m/s^-1. A fielder immediately runs in the opposite direction at a speed of 7m/s^-1 in time to catch the ball.

Calculate the distance travelled by the fielder.

Answer 1

$t=\frac{2v sin \alpha}{g},$

$l=Vt=\frac{2Vv sin \alpha}{g},$

$l=\frac{2\cdot 7\cdot 50\cdot 0.87}{9.8}=62~m.$
