Two different objects are moving with different velocities until they strike each other, stick to each other, and begin moving together. if each object’s mass is known and each object’s initial velocity is known, then the final velocity can be predicted using the law of conservation of a. energy b. momentum c. force d. speed

as they stick together, it is a totally inelastic collision so total momentum is conserved. ans is b. momentum.

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate
