Question

A car is moving with a speed of 60km/hr, starts from point A of a circular track and comes to the same point in time 10 min. The total displacement made by the car is ___________________. *


​

Answer 1

Answer:

total displacement of car is 0 (zero)

total displacement of car is 0 (zero)since displacement of a body is the minimum distance from its starting point to its end point

Answer 2

Given :-

Speed (s) => 60km/hr = 60×5/18 = 300/18 m/s

Time (t) => 10min = 10×60 = 600s

To Find :-

Displacement[diameter] => ?

Solution :-

DISTANCE = SPEED × TIME

=> 300/18 × 600

=> 120000/18 m

2πr = 120000/18

2πr = 6666.66..

2×3.14r = 6666.66

6.28×r = 6666.66

r = 6666.66/6.28

r = 1061.57 m

Displacement = 2r = 2×1061.57 = 2123.14m ...ans...
