#### A well-thrown ball is caught in a well-padded mitt. If the deceleration of the ball is 2.10×10^{4} m/s^{2}, and 1.85 ms (1 ms = 10^{-3} s) elapses from the time the ball first touches the mitt until it stops, what was the initial velocity of the ball?

**Solution:**

The formula in solving for the initial velocity is

Substitute the given values
