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?

  • Physics -

    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

  • Physics -

    So you just make the deacceleration the time?

  • Physics -

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

  • Physics -

    (CHANGE IN VELOCITY} /TIME

    as he said
