A runner is training for an upcoming marathon by running around a 112-m-diameter circular track at constant speed. Let a coordinate system have its origin at the center of the circle with the x-axis pointing east and the y-axis north. The runner starts at (x, y) = (56 m, 0 m) and runs 2.5 times around the track in a clockwise direction. What is the magnitude of his displacement vector? ............. Whar is the direction of his displacement vector? West...

a runner travels 1.5 laps around a circular track in a time of 50 s . The diameter of the track is 40 m and its circumference is 126 m. Find (a) the average speed of the runner and (b) the magnitude of the runner’s average velocity. Be careful here ; average speed depends on the total distance traveled, whereas average velocity depends on the displacement at the end particular journey

One of the 3. Two athlete's run clockwise on a circular track at constant (although different) speeds. athletes runs 5 laps/min and is in the inner most lane which is 30ft from the center of the circle. The second athlete runs 3 laps/min and is in the outer most lane that is 60 ft from the center point. How fast is the distance between the two runners changing when the first runner is in the 4 o'clock position and the...
