Suzie (of mass 52kg) is roller blading down the sidewalk going 36 mph. She notices a group of workers down the walkway who have unexpectedly blocked her path, and she makes a quick stop in 1.9 seconds. What is Suzies average acceleration? Answer in m/s^2. What force was exerted to stop Suzie? Answer in N.
I had converted miles to meters and divided it by the time in order to get the average, but the answer was incorrect. and for the second question I had multiplied the average by the weight, but that was also incorrect.
