A ball is moving towards the wall as shown in diagram then momentum is conserved

A wall moving with velocity 2 cms^(-1) towards the ball and ball is moving towards the wall with a velocity 10 cms^(-1) . It hits the wall normally and makes elastic collision with wall. The velocity of ball after collision with wall in cms^(-1) .

A small ball is hung by a string fixed to a wall. The ball is pushed away from the wall. The forces action on the ball are shown in the diagram. Which of the following statements is wrong?

A ball dropped onto a hard floor has a downward momentum, and after it rebounds, its momentum is upward the ball's momentum is not conserved in the collision explain.

A sphere rolling on a horizontal rough surface Collides elastically with a smooth vertical wall, as shown in Fig. State which of the following statements is true or false. a. After collision, the velocity of the centre of mass gets reversed. b. Angular momentum of the sphere about the point of contact with the wall is conserved. c. Angular momentum of the sphere about a stationary point on the horizontal surface is conserved. d. Just after collision the point of contact with the horizontal surface is moving towards the wall. e. After collision the friction force acts on the sphere such that it decreases the linear speed and increases the angular speed. f. Finally, when the sphere starts rolling, it is moving away from the wall.
