Why the change in momentum of the egg as it falls is the same magnitude as the change in momentum it undergoes when it stops?

Why the change in momentum of the egg as it falls is the same magnitude as the change in momentum it undergoes when it stops? Correct answer: Explanation: In both cases the egg starts with the same velocity, so it has the same initial momentum. In both cases the egg stops moving at the end […]

When a 50000 kg train car moving at 2 m s collides and connects to another identical car initially at rest?

When a 50000 kg train car moving at 2 m s collides and connects to another identical car initially at rest? A 50,000 kg train car moving at 2 m/s collides and connects to another identical car initially at rest. Find the velocity of the two cars immediately after collision. Answer: The final velocity of

Why an ice skater is able to increase her angular velocity by folding her arms?

Why an ice skater is able to increase her angular velocity by folding her arms? When the hands and legs are brought close to the rotational axis, the rotational inertia decreases thereby increasing the skaters angular velocity as per the conservation of angular momentum. Increase in angular velocity implies increase in the kinetic energy. Why
