Two snowballs with masses of 0.48 kg and 0.81 kg, respectively, collide head-on and combine to form a single snowball. The initial speed for each is 14 m/s. (One of them is negative since they are going in opposite directions.) What would the final speed of the combined snowball be?

Explanation:
When the medium is dense, the molecules in the medium are closely packed which means that the sound travels faster. Therefore, the speed of sound increases as the density of the medium increases.
