A sprinter reaches his maximum speed in 2.5sec from rest with constant acceleration. He then maintains that speed and finishes the 100m in the overall time of 9.60 seconds. Determine his maximum speed . 5. The cone falling with a speed strikes and penetrates the block of packing material. The acceleration of the cone after impact is = −

Respuesta :

The maximum Speed of the Sprinter from the velocity time graph of his motion is; 11.98 m/s

How to find the maximum speed?

We are given;

Initial Speed; u = 2.5 s

Total distance; d = 100 m

Total time; T = 9.6 s

The total distance is;

d = ¹/₂(9.6 + (9.6 - 2.5) * v

where v is maximum speed.

Thus;

¹/₂(9.6 + (9.6 - 2.5) * v = 100

16.7v = 200

v = 200/16.7

v = 11.98 m/s
