Ok so I have this problem which is most likely easy to all of you. The problem says that the first 10 meters of the 100 meter are covered in the first 2 seconds by a sprinter who starts from rest and accelerates with a constant acceleration. The remaining 90 meters are run with the same velocity the sprinter had after 2 seconds. a. Determine the sprinters constant acceleration during the first 2 seconds. I got 5 m/s b. Determine the sprinters velocity after 2 seconds have elapsed. I couldn't decide on 5 m/s^2 or 10 m/s^2 because i used Vf=Vo+at and V=d/t and it gave me those two different answers. c. Determine the total time needed to run the full 100 meters. I got 6.32s which is unrealistic. Please help me out I'm a little rusty just starting physics two and would love for you guys to solve and compare answers. Thank you!
