Answer 1

Answer:

1. distance = 1400+1400+1400+700

= 4900 m

and displacement will be the diameter i.e. 2800 m

2. distance = 1400 X 5

= 7000 m

and displacement will be 0

Answer 2

Answer:

(i) distance = (3 X 1400 m) + (1/2 X 1400m)

= 4200 m + 700 m = 4900 m

displacement in 1 round = 0. in 2 round = 0. in 3 round = 0. in half round = diameter = 2800 m

(ii) distance = 5 X 1400 m = 7000 m

displacement = 5 X 0 = 0 m
