Roland throws a 0.05kg egg with a velocity of 10 m/s to the right. The egg hits a wall and breaks. Which of the following is true?A. Momentum is not conserved because outside forces act on the systemB. The total momentum before the collision equals the total momentum after the collisionC. The momentum of the wall after the collision is 0.5kg m/s to the rightD. The momentum of the egg after the collision is 0.5kg m/s to the left

Sagot :

We are given that an egg is thrown against a wall. The initial momentum of th egg is:

[tex]p=mv[/tex]

Where "m" is the mass and "v" is the velocity. Whe n the egg hits the wall that is a force that acts on the egg. Therefore, the change in momentum is:

[tex]I=p_f-p_0[/tex]

This mean that the momentum is not conserved because there is an outide force that is causing an impulse "I". Therefore, the right answer is A.
