Question

A car is moving along a circular path with a uniform speed 54 kmph. Find the difference in the velocities of
the car when it is at the diametrically opposite points.
(1) 54 kmph
(2) 108 kmph
(3) 81 kmph
(4) 27 kmph
​

Answer 1

Explanation:

velocities are diametrically opposite points are opposite signs to each other.

so different in velocities

54 - (- 54)

= 54 + 54

= 108 kmph
