An object is moving towards a mirror with a velocity of `10 ms^(-1)` as shown in the figure. If the collision between the mirror and the object is perfectly elastic, then the velocity of the image after collision with mirror in vector form is

An object is moving towards a convex mirror with a constant velocity. P is the pole of mirror.

As an object moves towards a convex mirror, the image

A marble going at a speed of 2 ms^(-1) hits another marble of equal mass at rest. If the collision is perfectly elastic, then the velocity of the first marble after collision is

A point object O and a mirror M move with velocities of 3 cm s^(-1) and 4 cm s^(-1) , respectively as shown in the figure. OO' is the normal to the mirror. What is the velocity of the image?

An object is moving towards a stationary plane mirror wiyh a speed of 2 m/s. Velocity of the image w.r.t. the object is

A ball is moving with velocity 2m//s towards a heavy wall moving towards the ball with speed 1m//s as shown in figure. Assuming collision to be elastic, find the velocity of ball immediately after the collision.

Two balls each of mass 'm' are moving with same velocity v on a smooth surface as shown in figure. If all collisions between the balls and balls with the wall are perfectly elastic, the possible number of collisions between the balls and wall together is

Figure shows a plane mirror and an object that are moving towards each other. Find the velocity of image.
