Homework Answers
when the skater completes one lap then he is back to his original starting position. So no matter how many laps he skates, after each complete lap he will at his initial position, so linear displacement will be equal to zero.

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
