Solve the all parts of given question:

Question: The best sprinters can run a 100 m in 10.0 s. A 60.2 kg sprinter accelerates uniformly for the first 51.0 m to reach top speed, which he maintains for the remaining 49.0 m.

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

Part B: What is the speed of the sprinter over the last 49.0 m of the race (i.e., his top speed)?

I need help to find the average horizontal component of force exerted on his feet by the ground during acceleration.
