Question

Numbers that are used for counting

Answer 1

Given:

The initial velocity of the baseball is,

`u=0`

The final velocity of the ball is,

`v=31.2\text{ m/s}`

The time the ball is traveling for is,

`t=0.136\text{ s}`

To find:

The average acceleration of the baseball

Step-by-step explanation:

The average acceleration is,

`a=(v-u)/(t)`

Substituting the values we get,

`\begin{gathered} a=(31.2-0)/(0.136) \\ =229.4\text{ m/s}^2 \end{gathered}`

Hence, the average acceleration is,

`229.4\text{ m/s}^2`
