Two comets are moving directly towards each other. When they collide, comet A has three times the speed and one-third the mass of comet B.
Which of the following best describes the forces the comets exert on each other during the collision?

Choose 1
The forces exerted by each comet on the other are the same because interacting objects cannot
exert forces of different magnitude on each other.
The force exerted by comet A on comet B will be three times as great as the force exerted by comet
Bon comet A because comet A has triple the speed of comet B.
The force exerted by comet A on comet B will be one third the force exerted by comet B on comet
A because comet A has one third the mass of comet B.
