Homework Help: Physics

Posted by Tracy on Saturday, February 4, 2012 at 9:56pm.

Jamaican sprinter Usain Bolt holds the world record for the men's 100 meter dash with a time of 9.58 seconds. Another runner is training to break this record and finds that he can accelerate at a constant rate of 1.07 m/s^2. Assuming that the runner starts from rest, will he be able to break the world record?

a=v/t= the second runner dash with 9.76 seconds so no, he will not be able to break the record.

Is this right?
