A plane mirror coincides with a plane having equation x = 3. A particle is moving along a line with direction rations 3,4,5. If speed of the particle is `sqrt(2)`, the velocity of its image is

A particle is moving in X-Y plane that x=2t and y=5sin(2t). Then maximum speed of particle is:

A particle is moving along a line according to the law s=t^3-3t^2+5 . The acceleration of the particle at the instant where the velocity is zero is

The reflecting surface of a plane mirror is vertical. A particle is projected in a vertical plane which is also perpendicular to the mirror. The initial speed of the particle is 10m//s and the angle of projection is 60^@ from the normal of the mirror. The point of projection is at a distance 5m from the mirror. The particle moves towards the mirror. Just before the particle touches the mirror, the velocity of approach of the particle and the image is:
