Question

An Atlante completes a round of a circular track of diameter 200m in 20sec . write the magnitude of displacement of the athleteat the end of 1min

Answer 1

Answer:

displacement should be zero as the athlete completes three rounds of a circular track in one minute and returned to the original position he is starting from.

for distance 200=2r (where r is the radius)

r=100m

airport distance for 3 circular rounds will be 3x2πr=6x3.14x100=1884m
