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.
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
