Solve the all parts of given question:

Question: The 100-m dash can be run by the best sprinters in 10.0 s. A 70-kg sprinter accelerates uniformly for the first 45mm to reach top speed, which he maintains for the remaining 55mm.

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 55m of the race (i.e., his top speed)?

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