Hey guys,
im a physics junky, and new to these forums. I have a burning question i was thinking about the past week or so:
If a ball was bounced from a given initial height say 30m. And it bounced in a vacumm-tight container, would its velocity be high enough after its bounce to achieve...
Hello
I just have some basic question about the bouncing ball. When we throw a ball on the gound,
there is usual force of mg downwards, but since the ball is bouncing, due to the change in momentum, the ground will exert an upward force on the ball. Is this upward force same as the average...
A golf ball is hit from the fairway at a speed of 40 m/s at an angle of 45 degrees. Upon hitting the ground, the ball bounces off the ground at the same angle but loses 75 % of its speed on each bounce. How far does the ball travel before stopping ?
I started off with some trajectory and...
1. In baseball, player throws ball so that the ball takes one bounce before it reaches infielder.
Suppose that the angle at which a bounced ball leaves the ground is the same as the angle at which the outfielder launced it.

What is the equation to find the height of a bouncing ball under Earth's gravity (9.8?) if given the time (t) from the start of the drop (10ft) if the ball is either a tennis ball or a ball that reaches 1/2 of the previous max height? (Ignoring air resistance & spin) In addition, the angle of...

Hello, I am having a problem calculating the angular velocity of a bouncing ball.
At first this ball is thrown a distance and then hits the ground. Before it hits the ground it has no angular velocity. After it hits the ground it gets an angular velocity.

Force on a bouncing ball?
Homework Statement
this should be easy but for some reason I am making a mistake here is the problem

Ok, I am supposed to find the impulse of a .12 kg ball dropped from a height of 1.25 meters. It bounces back from the floor to a height of .6 meters. Not really sure of all the equations needed, I need a lot of help.
On earth, if I drop a ball from a building height 100m, what will be the maximum height of the ball after its first bounce? Note: This is not a homework question, I am trying to design a game and I want it to be as accurate as possible.

Bouncing Ball KE and momentum??
Does anyone know how to calculate the KE and momentum of a bouncing ball?
My quadratic equation is -4.113^t2+19.7t-22.72
The bounce begins at t=1.90s
the bounce ends at t=2.85s
The maximum height from my graph is (i think).8m.
For this exp I don't need...
A ball rolls off a table with initial velocity u (say 1m/s). Every time it hits the ground its velocity is halved. Find how many times it has bounced when it has traveled a distance x (say 1m) from the table.
I am almost sure that you can do this without knowing the height of the table but I...
