Force= Mass x Acceleration Acceleration= change in velocity/ change in time
Change in velocity = Vf - Vi
Average Velocity=displacement/time
a. Rakaya is driving her scooter to Fatema's house. Calculate the average velocity of Sarah when she travels 4500 meters on Warren
Avenue in 540 seconds.
b. While traveling down Warren Avenue, Rakaya suddenly comes to across a huge stuffed animal blocking the road. It took her 13
seconds to come to a complete stop. What was her acceleration as she slowed down? (Hint: Use change in velocity to figure out the
acceleration. Velocity initial is from a and velocity final is based on the words bolded above)
C. Unfortunately Rakaya hits the large stuffed animal as she stops. The scooter had a mass of 115 kg and Rakaya weighed 75 kg. With
how much force did they hit the stuffed animal?
