Asked by Sioraf

A baseball thrown at 25.0m/s strikes a catcher's mitt and slows down to rest in 0.500 s. What is the magnitude of the ball's acceleration?

I'm having trouble finding the process of figuring out this question. Help?

All you need to answer this is the DEFINITION of acceleration.

The acceleration is the speed change divided by the time. In this case, it is a negative number because the speed is decreasing.

a = (0 - 25.0)m/s /0.500 s = ___ m/s^2

So you just make the deacceleration the time?

Huh? a= -25/.5=-50m/s^2
