# Finding deceleration of a ball?

## 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.

a=(v-u)/t

I'm nit sure I understand the problem. What is the initial state of the ball before being hit?

The ball was at rest, and then it was hit by a bat.

Sorry!! I will include it in the above now.

Ok. And is the following information
mass=0.1kg
F=20N
is hit by a bat for 0.01s
has an acceleration of 200ms^-2
speed=2m per sec
travels 0.01m as it is hit by the bat
all given in the problem, or did you calculate some of those values?

The mass, force, and time was given in the question, and the remainder I calculated.
The ones I calculated are correct, when referring to the answers.

This is muddled. Please always post the question as it is asked (that's the only thing that should appear in the first section of the template). I don't understand the deceleration that is mentioned.

So, what exactly is the question being asked?
