Question

A ball of clay of mass m is thrown with a speed v against a brick wall. The clay sticks to the wall and stops. Is the principle of conservation of momentum violated in this example?

Answer 1

The principle of conservation of momentum is not violated in this example as the momentum is transferred from the ball to the wall.

Step-by-step explanation:

According to the principle of conservation of momentum, the total momentum of a system remains constant if no external forces act on it. In the given example, the ball of clay collides with the wall and sticks to it, causing the ball to stop. However, the principle of conservation of momentum is not violated because the momentum is transferred from the ball to the wall.

When the ball of clay collides with the wall, it exerts a force on the wall, causing an equal and opposite force to act on the ball. This transfer of momentum from the ball to the wall ensures that the total momentum of the system remains constant. Although the clay stops, its momentum is transferred to the wall, resulting in a change in momentum for each object involved in the collision.

Answer 2

Momentum is not conserved.

Step-by-step explanation:

Given that

mass of clay =m

initial velocity = v

We know that linear momentum P= m v

Initial momentum Pi= m v

The final velocity of clay and wall =0

That is why final momentum = 0

Therefore here momentum is not conserved.

So we can say that linear momentum is not conserve.

Actually when clay strike to the wall then after wall and clay move with some speed but this speed is very very small and we can not detect it.
