A football player kicks a ball of mass 1.534 kg across the field using a constant force of 13.4 N over a distance 30.0 m. How much work does the football player do? If the ball was initially stationary, what is its final speed?

Answer 1

Work = force * distance
= 13.4 *30 = 402 Joules

(1/2) m v^2 = 402

1.524 v^2 = 804

v = 22.9 m/s
