Question

A car is moving in a circular track of radius r(cm). The displacement of

the car after the completion of 1.5 round is ________.​

Answer 1

Answer:

2r

Step-by-step explanation:

displacement after 1 round = 0

.5 round = 2× r

Answer 2

Displacement of  the car:

1) The car is moving in the circular track so if the car completes a round of the circle then the displacement of the car is zero as the starting and end point of the circle is same.

2) but in the question it is given that the car completes the 1.5 round which means the car will reach at the end point of the diameter of the circle form the starting point.

So the displacement of the car will be 2r cm.
