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 hisfeet by the ground during acceleration?

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

(a)Compute the electrical conductivity of a cylindrical silicon specimen 7.0 mm (0.28 in.) diameter and 57 mm (2.25 in.) in length in which a current of 0.25 A passes in an axial direction. A voltage of 24 V is measured across two probes that are separated by 45 mm (1.75 in.).(b)Compute the resistance over the entire 57 mm (2.25 in.) of the specimen?
