Does the collision between the cart and the brick follow the law of momentum conservation? Make a claim (yes or no) and support the claim by describing the evidence and reasoning that that supports it

yes it does

Explanation:

Going by the law of conservation of momentum, when two objects collides, the momentum of one object is transferred to the other object.

This collision can be elastic or inelastic coliision

let the mass of the brick be m1

the mass of the cart be m2

the velocity (initial and final) of the brick  u1 and v1

the velocity (initial and final) of the cart u2 and v2

For elastic collision

m1u1+m2u2= m1v1+m2v2

For inelastic collision the two bodies will move with the same velocity after impact

m1u1+m2u2=(m1+m2)V

mass and volume are the answers you are looking for

reserve is the answer
