The 100- dash can be run by the best sprinters in 10.0. A 62- sprinter accelerates uniformly for the first 43 to reach top speed, which he maintains for the remaining 57 .

What is the average horizontal component of force exerted on his feet by the ground during acceleration?

What is the speed of the sprinter over the last 57 of the race (i.e., his top speed)?
