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
1
a) 2200 m
b) 700 m
c) 1400 m
d) 1500 m
​

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

Answer 2

⭐ 1400

Explanation:

✏ Displacement is defined by the distance between the final and initial position.

✏ Let the initial be 0

✏ As it cover a distance of semicircle ( but through circumcircle, it reaches to be point opposite their initial point.

➡ Hence,

⭐ Displacement = Distance =

2 × radius

⭐ Displacement = 2 × 700 = 1400m
