commuter backs her car out of her garage with an acceleration of 1.40 m/s2 . (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?
Step-by-step solution Step 1 of 4 The formula to find the acceleration is Therefore, Here is the final velocity, is the initial velocity and is the time. Deceleration is negative acceleration that occurs when the speed of an object decreases with time. Step 2 of 4 (a) Use the above formula, Substitute for , for and for . Therefore, the time that takes to reach a speed of 2.00 m/s . is Comment
