Question

A car moves in a semi circular track of radius 700m .if it starts from one end to the track and stops at the other end ,then the displacement of the car is

Answer 1

Circumference if one circular round =

$2\pi \: r$

2 × 22/7 × 700 = 4400

Now , since it was a semi circular track

Therefore, Displacement = 4400/2=2200

The answer may be wrong as well ..but if it helpsyou then it would be a pleasure fir me . Please make it the Branliest Answer

Answer 2

ANSWER:

Displacement of car = 1400 m

GIVEN:

A car is moving in a semicircular track of radius 700m

TO FIND:

Displacement of the car.

SOLUTION:

DISPLACEMENT: The length of the shortest path from the initial point to final point is called displacement.

Here;

displacement = 2 * radius

= 2 * 700

= 1400 m

SOME IMPORTANT FORMULAS:

$average \: speed \: = \frac{total \: distance}{total \: time} \\ average \: velocity \: = \frac{total \: displacement}{total \: time}$
