A cue ball mass 0.155 kg is at rest on a frictionless pool table The ball is hit dead center by a pool stick which applies an impulse of 1.75 Ns to the ball The ball then slides along the tabl?

the ball will roll across the table becaause there is 1/4 extra momentum to push the ball forward.

The cue ball will have a final velocity after the impulse is applied. Since no external forces act on it, its momentum will be conserved. You can calculate the final velocity using the impulse-momentum theorem: impulse = change in momentum = mass x (final velocity - initial velocity).

When a body slides over a surface the kinetic friction and static friction related as?
The kinetic friction is the force that opposes the motion of an object as it slides over a surface, while the static friction is the force that prevents an object from moving when at rest on a surface. Kinetic friction is generally weaker than static friction for a given surface.
When and object slides over a smooth horizontal surface how does the force of friction depend on the force of gravity on the object?
The force of friction is independent of the force of gravity on the object when it slides over a smooth horizontal surface. Frictional force depends on the nature of the surfaces in contact and the normal force, which is perpendicular to the surface of contact. The force of gravity affects the normal force, not the frictional force.
Where can one find inflatable water slides for the summer time?
Someone can find inflatable water slides for the summer time for sale from a number of companies such as Amazon. Amazon has a large selection of inflatable water slides for sale.
What is staining rack?
A staining rack is a laboratory tool used to hold and organize slides during the staining process. It typically has grooves or slots where slides can be securely placed to prevent them from moving or touching each other while applying different staining solutions. Staining racks help in efficient and uniform staining of multiple slides at once.
When one tectonic plate slides on one another?
earthquake
When is friction necessary for some type of movement to occur?
If a ball slides down a frictionless hill there will be no rotation of the ball. But with friction the ball will both translate and rotate down the hill.
A child slides down a frictionless slope at 25 degrees to the horizontal Calculate the child's acceleration down the slope?
a(child acceleration)=g(gravitational acceleration)*sin25=4.144 m/s2
What are some non examples of friction?
Friction is not present when an object slides along a frictionless surface, like ice. Friction is also not involved when objects are in free fall or moving through a vacuum, as there is no surface contact to create resistance.
A wooden block is released from rest at the top of a frictionless inclined plan and slides down to the bottomWhat convertions of energy are taking place as the block goes down the inclined plane?
As the wooden block slides down the frictionless inclined plane, potential energy is converted to kinetic energy. At the bottom of the incline, some of the kinetic energy will be converted back into potential energy due to the change in height. Overall, the total mechanical energy of the block (sum of potential and kinetic energy) remains constant throughout the motion.
In a 3D game a 4 kg object slides down a frictionless curved track from a height of 3.5 m what is the object's speed at the bottom of the track?
First of all..... I HATE APEX... they are the worst. I am using the kinematic equations... it is all i could come up with
How do you place a roller on a roller handle to paint?
The roller slides onto the handle from the side. Some handles have a nut that pust be unscrewed first, some have a spring that simply slides into the center of the roller.
What is the momentum of a 50 kg carton that slides at 4 meters per second across an icy frictionless surface?
momentum=mass*velocity(P=MV) P=50*4 P=200 kg m/s
When a body slides over a surface the kinetic friction and static friction related as?
The kinetic friction is the force that opposes the motion of an object as it slides over a surface, while the static friction is the force that prevents an object from moving when at rest on a surface. Kinetic friction is generally weaker than static friction for a given surface.
Which cannot be chosen while printing the slides in ms power point six slides five slides four or three slides?
Five slides, as there is no option to do so.
What are water slides?
slides with water
Can the corner window be replaced on a Ford F-250 sliding window?
no the only window that can be replaced is the center one that slides. in some sliders not all.
