#### A commuter backs her car out of her garage with an acceleration of .

(a) How long does it take her to reach a speed of 2.00 m/s?

(b) If she then brakes to a stop in 0.800 s, what is her deceleration?

**SOLUTION:**

a) The formula for acceleration is

If we rearrange the formula by solving for the t, in terms of velocity and acceleration, we come up with

b) The formula for acceleration (deceleration) is
