Final answer:
To calculate the momentum of the egg before collision, use the formula p = mv, where m is the mass and v is the final velocity obtained by the kinematic equation for free fall v = √(2gh).
Step-by-step explanation:
To calculate the momentum of the egg right before its collision with the ground, you would use the formula p = mv, where p represents momentum, m is the mass of the egg, and v is its velocity just before impact. Since the mass of the system (egg) is given as 3.0 kg, you need to determine its velocity just before the collision. You can find this velocity by using the kinematic equation for an object in free fall under the influence of gravity, which is v = √(2gh), where g is the acceleration due to gravity (approximately 9.81 m/s2), and h is the height from which the egg was dropped or the distance it fell. After calculating the velocity, multiply it by the mass to obtain the momentum just before impact.
