A sprinter running a 100-meter race starts at rest, accelerates at constant acceleration with
magnitude A for 2 seconds, and then runs at a constant speed until the end.
a) Find the position (relative to the start position) and speed of the runner at the end of the 2
seconds in terms of A.
b) Assume that the runner takes a total of 10 seconds to run the 100 meters. Find the value of
the acceleration A. You can leave your answer in terms of a fraction but clearly indicate the
units.
