## Homework Statement

How to find deceleration of a ball that is hit, given the ball:

mass=0.1kg

F=20N

is hit by a bat for 0.01s

has an acceleration of 200ms^-2 when hit by bat

speed=2m per sec

travels 0.01m as it is being hit by the bat

Was initially at rest.

## Homework Equations

a=(v-u)/t

## The Attempt at a Solution

Using the acceleration formula, I had swapped the positions of u and t, resulting in -200ms^-2, which is wrong. The answer is 2ms^-2, and I am not sure how to go about this. Please help me in getting this qu started! Thank you!
