Question

The three initial and final positions of a man on the x-axis are given as
(i) (-3 m, 7 m) (ii) (7 m, -3 m)
(iii) (-7 m, 3 m)
A. (i)
B. (ii)
C. (iii)
D. i) and iii)

Answer 1

Correct Answer - B
(b) : Displacement = Final position - Initial position
`delta x = x_2 - x_1`
Then,
(i) `delta x` = 7 m - (-3 m) = 10 m
(ii) `delta x` = - 3 m - 7 m = - 10 m
`delta x` = - 3 m - (- 7 m) = 10 m
