Multiply the force by the distance. The mass is irrelevant for this problem.

How much work is done on a 40 N rock that won't move when pushed?
Work = (force) x (distance)Without motion, there is no work, no matter how great the force.
A student pushed a box 32.0 m across a smooth horizontal floor using a constant force of 124 N. If the force was applied for 8.00 s how much power was developed to the nearest watt?
First you need to calculate the work required. This is simply force x distance in this case.Once you have that, divide the work by the time.
How do you measure force in safety shoe?
get a force meter The most common tests done on safety shoes are: - impact resistance - compression resistance - penetration resistance For impact resistance a weight is dropped on the the toe-cap. Then it's measured how much millimeter the toe cap was indented. For compression resistance a gradual force is applied on the toe cap until it breaks or a certain number of millimeters of indent is reached For penetration resistance a nail is pushed through the sole and the protective mid plate, again the indent and force applied is measured.
Which newtons law of motion should be used for the example of a fuel in a rocket ignites the force of the gas expansion pushes out the back of the rocket and pushes the rocket forward?
Newton's third law of motion can be used. This law of motion states that any force has an equal and opposite force. This can be proven by simply pushing away from a table. When you push you are putting a certain amount of force on the table. This force is pushed back (opposite) with the same amount of force (equal) pushing you away. In turn, you can say that when you push away from a table you are using as much force as it would take you to move yourself. The Bernoulli's principle would also apply. It states that a force applied to a fluid is transmitted equally throughout the fluid in all directions. (This only slightly applies to this question.)
Infer use newtons second law to determine how much force is being applied to an object that is traveling at a constant velocity?
If there is no force against motion,applied force is zero. If there is force against motion,applied force is equal and opposite to that force.
How much work is performed when a 60 kg crate is pushed 20 m with a force of 40 N?
400 J
How much work is performed when a 60 kg crate is pushed with 20 m with a force of 20 N?
400 J
How much work is performed when 100 kg crate is pushed 30 meters with a force of 40 newtons?
Multiply the force by the distance. The mass is irrelevant for this problem.
How much work is performed when a 25-kilogram crate is pushed 5 meters with a force of 15 newtons?
Work = (force) x (distance) = (15) x (5) = 75 joules.The mass of the crate is irrelevant.
How much work is performed when a 50 kg is pushed 15 m with a force of 20 N?
If a force of 20 N acts through a distance of 15 m, then it does (20 x 15) = 300 joules of work.The other facts of the case, such as the mass of the crate being pushed, don't matter.
If you apply a force of 220 N to the lever how much force is applied to lift the crate?
If the perpendicular distance from the point of application of the force to the fulcrum is x metres and the perpendicular distance from the crate to the fulcrum is y metres, then the force applied on the crate is 220*x/y N.
If a worker pushes horizontally on a large crate with a force of 298 newtons and the crate moved 6.5 meters how much work do he do?
Work = force x distance = Newtons x meters = 1937 Joules.
How much work is done when a 100N force pushes a crate 5m across a factory floor?
Work performed = Force x displacement = 100 x 5 = 500 J (joule)
How much work in joules is performed when a force of 800.0 N is exerted while pushing a crate across a level floor for a distance of 1.5 meters?
We must assume that the force pushes parallel to the floor.Work = (force) x (distance) = (800) x (1.5) = 1,200 newton-meters = 1,200 joules
What is comperession?
compression is the force pushed on and object. The formula for how much pressure during compression is: force/area.
Pull horizontally on a crate with a force of 140 N and it slides across the floor in a dynamic equilibrium How much friction is acting on the crate?
If the crate isn't accelerating ... i.e. sliding at a constant speed, not speeding up or slowing down ...then the forces on it are balanced. The pseudo-force of friction is 140N in the direction opposite toits speed.
How much work is performed when a 50kg is pushed 15m with a force of 20n?
That depends also on the direction of force, though it simplifies greatly if force is all the way applied exclusively in the direction of movement. Work doesn't depend on the mass too. Formula is(assuming the direction of applied force is the same as of displacement): W = F * r, where W - work, F - force, r - displacement. For given data, it will be: W = 20 * 15 = 300 J
