Dr. Drew runs 175 meters East for 70 seconds, then walks back 10 meters West in 20 seconds. What is his speed in meters/second for the entire trip?
A typical male sprinter can maintain his maximum acceleration for 2.0 s and his maximum speed is 10m/s . After reaching this maximum speed, his acceleration becomes zero and then he runs at constant speed. Assume that his acceleration is constant during the first 2.0 s of the race, that he starts from rest, and that he runs in a straight line. How far has the sprinter run when he reaches his maximum speed? What is the magnitude of his...
Bruce runs a 100m race. 5 seconds after the race started Bruce is 45 mi from the starting line and reaches his max speed, he runs at his max speed for the rest of the race. Bryce notices that he is 77 meters from the starting line 9 seconds after the race started. a. what is Bryce's max speed b. suppose Bryce runs for an additional Z seconds after reaching his max speed i. how far will Bryce travel during...
One simple model for a person running the 100 mdash 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 11.5 m/sin 2.74 s , what will be his total time?
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?

Circle Circumfer Circle Diameter r is radius Ц 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 average angular acceleration after 10.34...
