Homework Statement
A 50kg sprinter ran a 100m dash in 10.97s. This sprinter set the record for the 100m dash at normal altitudes. Assume that she accelerated uniformly for the first 12.0m and then traveled at a constant velocity to the finish line.
Homework Equations
a) What is the sprinter's maximum velocity
b) What average horizontal force did the sprinter's feet exert on the ground while accelerating?
The Attempt at a Solution
I don't really know where to start tackling this problem.
EDIT: Problem solved. I only really had trouble with finding the terminal velocity. The second part wasn't too hard.
