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

**drwls**, Sunday, April 11, 2010 at 2:13pmAll 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
