# A 300g ball at rest is struck with a bat with a force of 150N. If the bat was in contact with the ball, for 0.02 seconds, what is the ball's velocity?

$v f = 10 \frac{m}{s}$
$F \triangle t = m \triangle v$
$\frac{F \triangle t}{m} = v f - v i$
$\frac{150 N \cdot .02 s}{0.30 k g} = v f$
$v f = 10 \frac{m}{s}$
