Imagine a hard surface along xz plane to be fixed.A particle moving along the line 4x+3y-12=0 ,with a speed of 10m/s ,from the positive side of y -axis, approaches towards the plane and collides.If the coefficient of restitution be e = 0.75 ,then the speed of the particle after collision will be (in

A ball of mass m moving with a speed 2v_0 collides head-on with an identical ball at rest. If e is the coefficient of restitution, then what will be the ratio of velocity of two balls after collision?

A ball of mass 2kg moving with speed 5m/s collides directly with another ball of mass 3kg moving in the same direction with speed 4m/s. The coefficient of restitution is 2/3. Find the velocities of both ball after the collision.

A particle is projected along an inclined plane as shown in figure. What is the speed of the particle when it collides at point A ? (g = 10 m/s^2)

A particle of mass m is moving along the line y-b with constant acceleration a. The areal velocity of the position vector of the particle at time t is (u=0)

A small smooth disc of mass m and radius moving with an initial velocity 'v' along the positive x- axis collided with a big disc of mass 2m and radius 2r which was initially at rest with its centre at origin as shown in figure. If the coefficient of restitution is 0 then velocity of larger disc after collision is
