A body moves along a quadrant of a circle of radius (r ). The displacement and distance traveled are.

The perimeter of a quadrant of a circle of radius 'r' is :

The perimeter of a quadrant of a circle of radius 'r' is :

The length of the arc of a quadrant of a circle of radius r is

Find the perimeter of a quadrant of a circle of radius 'r'.

A particle travels along the arc of a circle of radius r . Its speed depends on the distance travelled l as v=asqrtl where 'a' is a constant. The angle alpha between the vectors of net acceleration and the velocity of the particle is

What is the perimeter of a quadrant of a circle of radius 'r' ?

A body completes one round of a circle of radius R in 20 second. The displacement of the body after 45 seconds is

The velocity versus time graph of a body moving along a straight line is as shown in figure. The ratio of displacement and distance covered body in 5 second is :-
