Question

a body covers a distance of Z metre along a semicircle part calculate magnitude of displacement and ratio distance to displacement​

Answer 1

Answer:

if a body covers a distance of Z metre along the semicircle it means that displacement will be the shortest distance between initial position to final position that will be equal to to the twice of radius i. e diameter.

Explanation:

the ratio will be :-

the circle is possible only when the circumference of circle is 22 and the the diameter of a circle is 7 we write it as π = 22/7

according to the question the Z distance is covered by a body along a semicircle therefore the ratio of distance to the displacement will be equals to π/2 or π:2
