The reflecting surface of a plane mirror is vertical. A particle is a project in a vertical plane also perpendicular to the mirror .the initial speed of the particle is 10m/s and the angle of project ${60}^0$ from the normal of the mirror. the point of projection is at a distance 5m from particle moves towards the mirror. just before the particle touches the mirror. the velocity of approving of the particle and the image is:

Q. The reflection surface of a plane mirror is vertical. A particle is projected in a vertical plane which is also perpendicular to the mirror. The initial velocity of the particle is 10 m/s and the angle of projection is ${60}^0$. The point of projection is at a distance 5m from particle moves towards the mirror . just before the particle touches the mirror. the velocity of approve of the particle and the image is :

Q. A plane mirror is placed along the vertical plane (yz-plane). If a particle is also projected in the vertical plane with speed of projection $10\text{m/s}$ and angle of projection as ${60}^{\circ }$ from the normal direction to mirror. The point of projection is at a distance of $5\text{m}$ from the mirror, and the particle is directed towards the mirror. The magnitude of velocity of approach of particle and image, just before the particle touches the mirror is

Q. A particle is moving with velocity ($\hat{i}+2\hat{j}+3\hat{k})m/s$. A plane mirror exists in the x - y plane. The mirror has a velocity $(\hat{i}+2\hat{j})m/s$. Velocity of the image (in $m/s$) is:

Q. A plane mirror is inclined at an angle $\theta ={37}^{\circ }$ with horizontal surface. A particle is projected from point $P$ (see figure) at $t=0$ with a velocity $v=20\text{m/s}$ at an angle $\alpha ={53}^{\circ }$ with horizontal. Assuming the particle does not collide with the mirror. If in time $t$ (in $\text{s}$), image will be momentarily at rest with respect to particle, Find $10t$.
