If two identical balls roll off the edge of a horizontal table top and one leaves traveling at twice the speed of the other then which ball hits the floor first?

Both ball hit the floor at the same time. They both have the same vertical acceleration component, i.e. gravity, at work on them. Both will fall with an acceleration of approximately 9.81 m/s^2. Their horizontal speed component plays no part in bringing the balls to the floor.

∙ 14y agoWhen a ball rolls off a table, the time it takes to hit the ground is a function of the height of the table, not of the initial speed when it rolls off the table. So no, the time does not depend on the speed of the ball. Check out the equation that states that the time it takes an object to reach the ground equals the square root of ((2*distance dropped)/gravitational constant). A reasonable value for the gravitational constant would be 9.8 m/s^2. This is assuming that you are not worrying about resistance from the air.

then they both hit the floor at the same exact time.
They don't even have to have the same mass or weight.

What is the total momentum between two identical balls traveling toward each other at the same speed from opposite directions?
They have identical momentum before the collision . The total momentum will the the same before and after the collision. When the balls collide they will bounce apart both with same force and so the same momentum as originally - but in opposite directions. This assumes no energy loss in an ideal elastic collision.
What the momentum between two identical balls traveling toward each other at thae same speed from opposites direction?
The momentum of one ball will be exactly the opposite of the momentum of the other ball. The total momentum in this case will be zero.
When a ball is traveling at a constant velocity of 50 ms and has been traveling for over 2 minutes what is the balls acceleration?
When something is traveling at a constant velocity it has no acceleration. In other words your answer is 0.

Why do balls bounce in a parabola?
because: * the force of gravity is constant and downward * the acceleration due to gravity is therefore a result of the square of time * horizontal acceleration is zero so the horizontal velocity is constant * y=vyt -at2 x=vxt all this makes a parabola that opens downwards.
If you have 9 identical balls all weighing 100 gms except one which is 101gms?
Then the one weighing 101 gms isn't part of the 'identical' balls.
