Question

A body moves along a circular path of radius 10m what is the distance travelled and displacement when it completes half a round and 1 round

Answer 1

Answer:At half a round

Distance=10πm and displacement=π

At a 1 round

Distance=20πm and Displacement=2π

Explanation:Since the body is moving in a circular path it posses circular motion.That means the angular displacement is the angle subtented my a body from moving one point to another point in a circular path So displacement =distance/radius.For finding distance,distance=circumference of a circle(2πr)

[NOTE:In a half round you can use circumference of semi circle i.e πr]
