Integrated Concepts When starting a foot race, a 70.0-kg sprinter exerts an average force of 650 N backward on the ground for 0.800 s. (a) What is his final speed? (b) How far does he travel?
Solution 44 PE
Step 1 of 2
The final speed of the sprinter can be found using kinematic equation for one dimensional motion.
where, initial speed = 0 m/s
acceleration in m/s2
Now, we can find the acceleration using Newton’s second law of motion
where, F = Force exerted by the sprinter = 650 N
m = mass of the sprinter = 70 kg
a = acceleration
= 9.28 m/s2
