A point traversed 3/4 th of the circle of radius R in time t. The magnitude of the average velocity of the particle in this time interval is

A particle travels two and a half revolutions of the circle of radius R in time t. The ratio of the average speed of the particle to the magnitude of the average velocity in this time interval is

A particle travels two and a half revolutions of the circle of radius R in time t. The ratio of the average speed of the particle to the magnitude of the average velocity in this time interval is

If magnitude of average speed and average velocity over a time interval are same, then

If magnitude of average speed and average velocity over a time interval are same, then

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.

Starting from rest, a particle rotates in a circle of radius R = sqrt 2 m with an angular acceleration = pi/4 rad/s2.The magnitude of average velocity of the particle over the time it rotates quarter circle is:

Starting from rest, a particle rotates in a circle of radius R  2 m with an angular acceleration  = /4 rad/s2.The magnitude of average velocity of the particle over the time it rotates quarter circle is:
