Question

a circular track has a circumference of 3140m with AB as one of the diameter. a scooterist moves from A to B along the circular path. Find his distance and displacement.What will be displacement if he covers 3 quarters of the circle?

Answer 1

distance = 3140*3/4
=2355m
displacement
circumfrence =2*22/7*r
3140=2*22/7*r
3149/6.28=r
500=r
now
h^2=b^2+P^2
= 500*500+500*500
=250000+250000
=500000
H^2=500000
h=707.1m
displacement =707.1
