Then its kinetic energy is the same before and after the bounce . . . 64 joules . . .
and its momentum has the same magnitude after as it had before . . . 32 kg-m/s . . .
but in the opposite direction.
The bouncing of a ball is influenced by factors such as the material of the ball, the surface it bounces on, the force with which it is thrown or dropped, and the elasticity of the ball. These factors determine how high the ball will bounce and how many times it will bounce before coming to a stop.
The physics equation used to calculate the trajectory of a bouncing ball is the coefficient of restitution formula, which is given by the equation: v2 e v1, where v1 is the initial velocity of the ball before it bounces, v2 is the velocity of the ball after it bounces, and e is the coefficient of restitution that represents the elasticity of the collision.
When a ball bounces off a table, the initial potential energy is converted to kinetic energy as the ball falls towards the table. Upon impact, some of this kinetic energy is converted back into potential energy as the ball compresses slightly, before being translated back into kinetic energy as the ball bounces back up. Some energy is also lost to sound and heat during the bouncing process.
We have to assume that it exactly reverses its direction, so that a video of the wholeevent would look exactly the same whether it's played forward or backward.Momentum = m VWhen the ball is approaching the spring, its momentum is mV = (8)(2) = 16 kg-m toward the wall.After the bounce, the momentuim of the ball is mV = (8)(-2) = -16 kg-m toward the wall,or +16 kg-m away from the wall.The change in momentum is 32 kg-m .We are momentarily chagrined at the realization that we can't figure out wherethe 32 kg-m went/came from, to keep the initial and final vector momenta equal.Hopefully another contributor will be able to pop in and put it to rest.
A bouncing ball has its greatest potential energy at the highest point of its trajectory when it momentarily comes to a stop before starting to descend back down.
It bounces 134 times before it stops.
As long as it goes 10 yards before bouncing back it is a legal kick
bouncing the ball at room temperature, before heating or freezing it, and then measuring the height of the bounce.

The term for hitting the ball before it bounces in a game is called a "volley."

Open bowling is either before or after league bowling. Call ahead before going to the bowling alley.
Yes, if the ball bounces more than twice it is a no ball but if it bounces twice it is legal. Although this is a very unlikely situation.
No
