Momentum is a fundamental concept in physics that describes the motion of an object. It is calculated by multiplying an object's mass by its velocity. In the given scenario, the momentum of the bullet just before hitting the bag can be calculated using the equation:
momentum = mass x velocity.
Given that the mass of the bullet is 20g (or 0.02kg) and its velocity is 200m/s, we can determine the momentum just before impact.
Moreover, the average force that stopped the bullet can be determined using the equation:
average force = change in momentum / time.
Since the bullet comes to rest in 0.011s, we can calculate the average force it experienced during that time.
Understanding momentum and calculating it helps analyze the impact and forces involved in various scenarios, which is crucial for comprehending the laws of motion and the principles of physics.
