From the relation between the linear and angular quantities we know that
V=r*W
V is linear velocity
r is radius of the curvaacur
W is angular velocity
Substituting the values
W= V/r
W= 4/36.3 rad/s
W= 0.1102 rad/s
So the angular velocity at t=3.44s is W= 0.1102rad/s

Circle Circumfe Circle Diameter r is radius Finish A sprinter runs the curve of this 200 m in 10.34 s. Assume he ran in a lane which makes a semicircle (r 36.3 m) for the first part of the race. At 3.44 s into the race his speed is 4.0 m/s. At 8.0 s into the race his speed is 9.6 m/s. His speed after the curve was 12.8 m/s. What was the sprinter's radial acceleration at 3.44 s? Answer:...

One simple model for a person running the 100 m dash is to assume the sprinter runs with constant acceleration until reaching top speed, then maintains that speed through the finish line. If a sprinter reaches his top speed of 10.8 m/s in 2.54 s, what will be his total time?
