A particle in motion covers half of a circular path of radius r in time t . Find the average speed and average velocity of the body.

A ball moves one-fourth ((1^(th))/(4)) of a circle of radius R in time T. Let v_(1) and v_(2) be the magnitudes of mean speed and mean velocity vector. The ratio (v_(1))/(v_(2)) will be

Assertion: Average speed of a particle in a given time interval is never less than the magnitude of the average velocity. Reason: The magnitude of the velocity (instantaneous velocity) of a particle is equal to its speed.
