Review Careful measurements have been made of Olympic sprinters in the 100-meter dash. A quite realistic model is that the sprinter's velocity is given by Ua(1-e- where t is in s, Ux is in m/s, and the constants a and b are characteristic of the sprinter. Sprinter Carl Lewis's run at the 1987 World Championships is modeled with a - 11.81m/s and b- 0.68875 Part A What was Lewis's acceleration at t0s? Express your answer using four significant figures Submit...
