How does changing the amplitude affect the energy of the wave

A wave can be simply defined as a disturbance that can propagate from one place to another and in doing so, it carries energy and is comprised of a definite wavelength and amplitude. These waves can be of high or low energy.

In a wave, there is a direct relationship between the amplitude and the energy as the energy is directly proportional to the double of its amplitude. This means that increasing the amplitude of a wave, the energy increases by double of it. And if the amplitude decreases then the energy abruptly decreases.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer
