Respuesta :

Answer: Choice B: baseball bat; increases velocity

Explanation:

I got this right on my test !!!!!!!

Answer:

" baseball ; increases velocity ".

Explanation:

A lever is a type of simple machine. There are three classes of lever i.e. first class, second class and third class.

Baseball bat is an example of third class lever. Its mechanical advantage of less than 1. In this type of lever, the input force is located between fulcrum and output force. It increase distance but do not change the direction of input force. As a result, velocity increases.

So, the correct option is (b) " baseball ; increases velocity ".
