A sprinter runs the curve of this 200 m in 9.73 s. Assume he ran in a lane which makes a semicircle (r = 32.4 m) for the first part of the race. At 3.08 s into the race his speed is 4.1 m/s. At 7.3 s into the race his speed is 9.6 m/s. His speed after the curve was 11.6 m/s. A sprinter runs the curve of this 200 m in 11.13 s. Assume he ran in a lane which makes a semicircle (r = 30.4 m) for the first part of the race. At 4.64 s into the race his speed is 6.9 m/s. At 7.9 s into the race his speed is 9.5 m/s. His speed after the curve was 11.4 m/s. What is the sprinter's angular displacement at 11.13 s? Answer in radians. Answer: Question 1 What was the sprinter's radial acceleration at 7.3 s?
