Two magnets are sliding towards each other. one of the magnets, which has a mass of 125 grams, is moving in the positive x-direction at a speed of 7.33 m/s. the other magnet, which has a mass of 85.0 grams, is moving in the negative x-direction at a speed of 11.9 m/s. when they collide, they bind together and move as a single unit. what is the velocity of this single unit immediately after the collision?

0.45 m/s in the negative x-direction

Explanation:

From the law of conservation of momentum, the sum of initial momentum equals the sum of final momentum

Momentum, p=mv where m is the mass and v is the velocity

where is the common velocity, and are velocities of magnet moving in positive x-direction and magnet moving in negative x-direction respectively, and are masses of magnet moving in positive x-direction and magnet moving in negative x-direction respectively.

Substituting 125 g for and 85 g for , 7.33 m/s , -11.9 m/s for then

Therefore, the velocity of single unit is 0.45 m/s in the negative x-direction

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
