Question

a body moves along a circular path of diameter 7m.calculate the distance and displacement after it has covered one and a half revolution

Answer 1

Answer:

Explanation:

Given,

Diameter of circular path = 7m

Radius (r) = 7/2m

For a complete revolution

Distance = circumference of circular path = 2πr

2 × 22/7 × 7/2

= 22 m

Displacement = 0 ( because initial and final point is same

For half revolution

Distance = Displacement = 2πr/2

22m/2 = 11m
