Question

A particle is moving in a circle of diameter 5 m . What is its displacement and distance when it completes 1 ½ revolutions?

Answer 1

Answer:

When the particle completes 1 revolution, then the displacement is zero. Now, in the next half revolution, the displacement is equal to the diameter of the circle. Thus, total displacement of the particle is; Displacement = 5 m.

Answer 2

Answer:

distance = 22.55 and displacement = 5

Explanation: distance = 2*3.14*5/2 +3.14*5/2

= 15.7 + 7.85

=23.55

displacement = 5
