7. a figure skater skating across ice, who grabs another skater and brings him along the ice with her, is an example of what type of collision? a. inelastic collision b. elastic collision c. mass collision d. parallel collision

The type of collision is A. Inelastic collision.

Explanation:

The macroscopic collisions are generally inelastic and do not conserve the kinetic energy, although of course the total energy is conserved. The inelastic collision is one in which the objects that collide remain together after the collision.

So, a figure skater skating across ice, who grabs another skater and brings him along the ice with her is a clear example of inelastic collision.
