\[a=\frac{dV}{dT}\]which basically means it's equal to rate of change in velocity. Only one of the above actually has a change in velocity. Can you figure out which one?

I'm guessing either the Speed Skater or the Ball..

The ball. You have to remember that velocity is a vector and therefore has both a speed and a direction. In the case, the ball is moving around a circular track...so it's direction is always changing. If the direction is changing so is its velocity...so it must have an acceleration.

Oh I get it. The other things change direction. The car is iffy but it could urn down another street. Could you help me with a few more?
