The horizontal velocity will be equal to the translational velocity of the ball right before it falls off the table.
==============================
When we do exercises that deal with the behavior of the ball after it leaves
the edge of the table, we always ignore air resistance. When we do that, the
horizontal component of velocity remains constant forever, or at least until the
ball hits something.
What else can I help you with?
A ball rolls off the end of a table with a speed of 2 mpers It hits the ground after 3 s If the tableop is 1 m from the floor what was the horizontal distance from the end of the table traveled by?
Hold up, whoa ! Just wait a second there.If the table-top is 1 meter from the floor, then the ball hits the floor 0.45 seconds after itrolls off the edge of the table. The horizontal speed makes no difference.A cannonball fired horizontally from the cannon and a cannonball dropped from the muzzleof the cannon hit the ground at the same time. Horizontal speed doesn't keep anything upany longer than if it drops straight down with no horizontal speed.If the ball is rolling horizontally along the table at 2 m/s, then it falls to the floor 0.45 secondsafter it reaches the edge, and in that period of time, it sails (2 x 0.45) = 0.9 meter out past theend of the table.
A ball rolled across a horizontal table moves at constant velocity.why?
The ball moves at a constant velocity because there are no external forces acting on it to change its speed or direction. The absence of any net force means there is no acceleration, allowing the ball to maintain a steady velocity. This state of motion is in accordance with Newton's First Law of Motion.
Why does a ball move in a straight line rolling on a table but follows a curved path once it rolls off?
The curved path is the result of gravity and inertia acting on the ball. As it leaves the table gravity pulls it to the ground at an increasing rate while inertia keeps it moving in its original direction. The table prevents the rolling ball from falling thus negating that curvature caused by gravity, and making it follow a straight line.
If a ball rolls off the edge of a table two meters above the floor and with an initial velocity of 20 meters per second what is the ball?
The time it takes for the ball to hit the floor is approximately 0.64 seconds.
What is the momentum of a 25 kg table?
To calculate momentum, you need both the mass and velocity of the object. If you provide the velocity of the table, we can calculate the momentum using the formula: momentum = mass x velocity.
What is the horizontal line on the periodic table?
The Horizontal row on the table is called a period
How fast must a ball be rolled along the surface of a 70cm high table so that when it rolls off the edge it will strike the floor at the same distance from the point directly below the edge of table?
(ignoring air resistance.) s = 0.7 metres take g = 9.82 (m / s) / s time to fall 0.7 metres, regardless of horizontal velocity, t = (sq. root (s / (0.5 * g))) = 0.3776 seconds so constant horizontal velocity required to travel 0.7 metres in 0.3776 seconds = 0.7 / 0.3776 = 1.854 metres / second

Are periods on the periodic table horizontal?
Yes. the horizontal rows on the periodic table are called periods.

What are the horizontal rows elements called on a periodic table?
The horizontal rows are periods on periodic table. There are 7 horizontal rows in modern periodic table.
What is the horizontal row across the periodic table?
A horizontal row on the periodic table of elements is called a period.
The horizontal row on the period table is called a(n)?
The horizontal rows in the periodic table are called periods
What is a horizontal series of cells in a table called?
A horizontal series of cells in a table is usually called a "row". A vertical series of cells in a table is usually called a "column".
What are the horizontal from left to right parts of the periodic table called?
The horizontal rows are referred as periods. There are 7 periods in periodic table.
What are the rolls of periodic table called?
The horizontal rows in the periodic table are called periods, and the vertical columns are called groups or families. Periods indicate the number of electron shells an element has, while groups determine the number of valence electrons.
What do you call the horizontal sections of the periodic table?
The horizontal sections of the periodic table are called periods.
