Question

question 10 of 25
a dart is thrown and sticks in a dart - board. what type of collision is this?
a. elastic collision
b. perfectly inelastic collision
c. reverse collision
d. inelastic collision

Explanation:

In a perfectly inelastic collision, the objects stick together after the collision. When a dart sticks in a dart - board, the dart and the dart - board move as one unit after the collision, which is the characteristic of a perfectly inelastic collision. In an elastic collision, kinetic energy is conserved and the objects do not stick. There is no such standard term as "reverse collision" in basic collision theory. An inelastic collision is a more general term, but when the objects stick together it is specifically a perfectly inelastic collision.

Answer:

B. Perfectly inelastic collision
