Question

A girl is standing still in the middle of a baseball field. The girl catches the baseball and begins to move in the same direction as the thrown ball. What type of collision is being described? inelastic, since the girl moves in the same direction as the thrown ball inelastic, since the girl moves in the opposite direction of the thrown ball elastic, since the girl moves in the same direction as the thrown ball elastic, since the girl moves in the opposite direction of the thrown ball

Answer 1

Answer:

inelastic, since the girl moves in the same direction as the thrown ball

Explanation:

When two bodies collide then after collision if two bodies separate from each other and move with two different velocities then this is an example of elastic collision.

While if two bodies collide and after collision they stick with each other and moves in same direction with same velocity then this is an example of perfectly inelastic collision.

So here in the given case ball is caught by the girl and that the ball and girl move together with same speed in the initial direction of motion of ball. This shows the situation of perfectly inelastic collision

So here correct answer will be

inelastic, since the girl moves in the same direction as the thrown ball

Answer 2

The answer to this question is the first option which states that, inelastic since the girl moves in the same direction as the thrown ball. Inelastic collision involves two or more bodies sticking together and moving as one mass after the collision. In this collision the kinetic energy is not conserved but the momentum is conserved.
