Question

on a 100m straight track,an athlete completes the race from the starting line up to the final in a particular time.calculate distance travel and magnitude of displacement

Answer 1

The distance travelled and displacement would be same since it is straight line track 100 m.  

Given:

Given data suggests that there is an athlete who completes a run of 100 m on a straight track.  

Solution:

The track race is completed in a particular time. So as given the track was of 100 m and the race was completed to the final line from the starting line so the complete race was of 100 m thereby the distance travelled by the athlete be 100 m.  

The displacement is a vector quantity and thus the magnitude of displacement is equal to the distance because the track was straight in path. So, displacement be 100 m.
