Question

BRRAINLIST AND 70 POINTS Suppose that a cart is moving along a road at a constant velocity. Give two examples of ways to cause the cart to decelerate, explaining how the net force is affected. (2 points)

Using two billiard balls, in 3-4 sentences, design an experiment to demonstrate the law of conservation of momentum

Answer 1

Step-by-step explanation:

The experiment can be performed by first setting up two billiard balls of equal mass on a frictionless surface. The first ball should be stationary while the second ball is given an initial velocity in the opposite direction of the first ball. After the two balls collide, we will measure the velocity of both balls after the collision. If the law of conservation of momentum holds true, then the initial momentum of the two balls should be equal to the total momentum of the two balls after the collision. This can be easily determined by measuring the velocity of the two balls after the collision and calculating the momentum using the equation momentum = mass x velocity.

Answer 2

The experiments to demonstrate the conservation of momentum with the two billiard balls of known masses, m₁ and m₂, and velocities u₁ and u₂. The balls are then made to collide with velocities v₁ and v₂ after the collision

The momentum before and after the collision is then calculated as follows:

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

What is the momentum of a body?

The momentum of a body is the product of the mass and the velocity of the object.

Mathematically;

the momentum of a body is determined as follows:

Momentum = mass * velocity

Momentum is conserved if the momentum before and after the collision is equal.
