what ball would bounce the highset?

The lightest and the smallest.

the one with greater elasticity.

To determine which type of ball would bounce the highest, we need to consider a few factors:

1. Elasticity: The more elastic the ball is, the higher it will bounce. Elasticity refers to the ability of an object to regain its shape after being compressed or stretched. A ball with high elasticity will compress upon impact and then quickly regain its shape, resulting in a higher bounce.

2. Material: The material from which the ball is made plays a significant role in its bounce. Generally, materials like rubber or latex give a higher bounce due to their elasticity. These materials can store and release more energy upon impact, leading to a higher rebound.

3. Pressure: The internal air pressure of the ball can affect its bounce. Inflating a ball to its recommended pressure maintains its shape and elasticity, resulting in optimal bounce. Overinflating or underinflating the ball can compromise its bounce height.

So, based on these factors, a ball made of highly elastic material such as rubber or latex, properly inflated to the recommended pressure, would typically bounce the highest. Additionally, a ball specifically designed for bouncing, such as a rubber bouncy ball, would also provide a high bounce due to its optimized construction.
