Yes, It does Alot Higher
A tennis ball is made of materials that are more elastic than a basketball, allowing it to deform and rebound quicker upon impact, resulting in a higher bounce. Additionally, the size and weight difference between a tennis ball and a basketball also contribute to the tennis ball bouncing higher.
A heated tennis ball bounces higher because the hot air inside the ball is lighter than the air around the ball therefore giving the tennis ball the ability to bounce higher.
A ladder is simply the rankings of tennis players. For instance on the laddder on my tennis team I am number 2, this means that there is only one person higher than me and plenty of people lower than me.
The air pressure inside the can is always higher than the air pressure outside the can. The air is compressed into the can along with the tennis balls.
