Question

A car moves in a semi circular track of radius 700 m. If it starts from one end of the track and stops at the other end, then the displacement of the car is
a)2200m
b)700m
c)1400m
d)1500m​

Answer 1

Answer:

1400

Explanation:

Displacement is defined by the distance between the final and initial positions.

Let initial be 0.

As it covers a distance of semi circle( but through circumference ), it reaches to the point opposite to the initial point.

Hence,

displacement = diameter = 2*radius

Displacement = 2*700 m = 1400 m
