Question

during a 100m race an athlete moving at an acceleration of 20m/s^2 stumbled on a stone and fell. he spent 10 seconds ont he floor before bouncing back on his feet for the race. is it possible for this athlete to over take his opponent who is running ata speed of 15m/s^2

Answer 1

Answer:

Initial velocity = 0

Final velocity vf.

a = 2 m/s2

Maximum speed = at = 20 m/s2

Maximum K.E.

(Assume m = 50 kg)

If it run with constant velocity v = 10 m/s

Then K.E.

So it lies between 2500 to 10,000 J.

Correct option is 1
