Question

. A body moving along a circular path of radius 21m describes an angle of 60 degree at the center of the circle while moving from A to B. If the time taken is 10 sec then find average speed and average velocity

Answer 1

Explanation:

For a body moving along a circular path, its displacement can at maximum be 2r (when the object has moved to the other end of diameter) and minimum can be zero, but the distance travelled by the object is along the arc of the circuit which is always greater then the displacement.

And, Averagevelocity=

Totaltime

Totaldisplacement

Averagespeed=

Totaltime

Totaldistance

∴Averagespeed>Averagevelocity

Answer 2

Explanation:
