How much work is don when a force of 50.5 n applied to table causes if to move 8 meters?

work done is defined as force applied (newtons) * distance travelled (metres)
in this case 50.5 n * 8m = 404 joules.
note:
if you divide it by the time taken, for example 2 seconds, this gives power (in watts)
so (50.5 n * 8m) / 2 seconds
= 202 watts

To stop a table in your classroom falling through the floor what must the floor do against the force of gravity pulling the table down?
Newton's third law of motion states that: "For applied force (A), exists some force (B) of equal magnitude acting in the opposite direction of the force applied.". The force of the weight (which is the mass of the table multiplied by gravity) [W=mg] pushing down on the floor is counterbalanced by an equal and opposite force of the floor pushing up on the table. This is why the table does not fall through the floor. The floor is able to provide this force without allowing the table to move through it because the bonds between its atoms are strong enough.
There are 9 newtons on a table The book occupies an area that is 0.3 square meters What is the pressure exerted by the book on the table in pascals?
Pressure = Force/Area Pressure = 9 Newtons/0.3 m2 Pressure is 30 Pascals
A blocks weight is 36.0 N rests on horizontal table A horizontal f. of 42 N is applied to the block coefficients of static and kinetic fric are 0.650 and 0.420 resp Will the block move under force?
In order for the block to move the force applied has to be greater than the maximum force of static friction. F > fs fs = coefficient of friction * normal force = .65 * 36N // you can use the weight for the normal force since the block is being supported = 23.4N Since applied force of 42N is greater than the 23.4N due to friction, the block will start sliding, where kinetic friction will act on the block.
What is the force of gravity on a 24kg table?
The force of gravity on a 24 kg table on earth = 24 x 9.8 = 235.2N
How many meters space you need to put one 9 feet pool table?
9 feet = 2.7432 meters(1 foot = 0.3048 meters) So you'd need about 2 meters and 75 centimeters to fit that pool table.
How much work is done when a force of 75 N applied to a table causes it to move 8 meters?
The application of 75N of force through a distance of 8 meters results in 600 newton-meters = 600 joules of work.
Why a man lifting a box to be placed on a table is work?
He applied a force to the box and it moved. Force applied on it equals to the weight. As he lifts the point of application of the force gets displaced. Hence work is said to be done.
When studying the effect of an applied force on the motion of an object why do you place the object on a level table top?
So that all of the motion you observe is the result of the force you applied, and none of it is the result of gravity.
When two people together simultaneously push the table in the same direction the force applied is what?
It is the sum of the forces applied by each

What type of force is needed to cause a static object object to start moving?
A push or a pull
Is there greater pressure on a table that is 9 square meters under 18N of force or on a table that is 16 square meters and is under 32N of force?
Pressure = force/areaP1 = 18N/9m2 = 2 N/m2 or 2 PaP2 = 32N/16m2 = 2 N/m2 or 2 PaP1 = P2, the pressures are the same.
Because of a frictional force of 100 N a force of 1 meter must be applied to a textbook in order to slide it along the surface of a wooden table What is the unbalanced force on the book?
0.2 N
Why is the upward force applied by a table on book kept on it called a self-adjusting force?
When the book is on the table the force of gravity tries to pull it down to the center of the earth. But according to Newton's third law of motion the every action has an equal and opposite reaction. Thus the table applies the same force on the book as well. This is called a self-adjusting force as the table tries to remain in its original state i.e. its lowest potential state.
A block of mass m=2.50kg is pushed a distance d =2.20m along table by a constant applied force of magnitude F=16.0N directed at an angle =25.0belew the horizontal as shown in Figure . Determine the work done on the block by a- the applied force?
87
If you exert a force of 4.5N on a book to slide it across a table and do 2.7J of work in the process how far have you moved the book?
Work Done = Force x Displacement 2.7 joules = 4.5 newtons x Displacement(in meters) Displacement = 0.6 meters
Is gravity the force applied up or down on an object?
Gravity pulls things downwards, so it is pointed downwards. If an object is resting on something (like a book resting on a table) an equal force will point upwards and that force is known as the normal force.
