How much force was applied to a box that requires 45 joules of work to push it up a 3 meter long ramp?

Work is done when energy is transferred
Lifting a box tranfers energy from the lifting device to the box giving it Gravitational Potential energy
The equation for GPE is mass (kg) x "gravity" (10m/s^2) x height (m)
The equation for Work is very similar!!
Work done = Force (N) x distance moved (m)
where Force (N) can be calculated from F=ma ------ Force = mass x acceleration!
Which put together gives us
Work Done = (mass (kg) x acceleration (m/s^2)) x distance moved (m)
In your example mass = 20kg
So the Force is 20 x 10 = 200 N
Thus the work done = 200 x 5 = 1000 J

∙ 13y agoFirst of all, without a pulley or lever system of some kind, you can't even do that
on earth. Around here, a mass of 3.5 kg weighs about 34.3 newtons. So, without
some machinery to multiply your force, you can't hold it at a constant height with
only a 15-N force.
To answer the question . . . When the force you provide doesn't move, such as when
you push on a wall or hold a load at a constant height, then no matter how tired
your muscles become or how much you perspire, no work is done according to the
formal physical definition of 'work'.
Work = (force) multiplied by (distance through which the force moves).
If either the force or the distance is zero, then the work is zero.
thank you the answer is greatly appreciated!

∙ 15y ago450 Joules of energy are needed to lift a 15 kilogram mass 3 meters off the ground.
Wiki User
∙ 14y agothe potenial energy will be their in lifting up the mass to 15 metres, so the potential energy will be..
30*15*9.8
= 4410 joules
Wiki User
∙ 13y agoPotential energy = mgh (mass x gravity x height). In this case, mass = 1, height = 1, and gravity is about 9.8.
Wiki User
∙ 10y agoPlease use the basic definition of work:
work = force x distance

How many joules of energy does a 1 Newton book gain when it is elevated 4 meter?
You need to multiply the force by the distance.
A force of 30N exerted over a distance of 3M does how much work?
In this case, you simply multiply the force times the distance. This assumes the 15 Newtons are applied exactly in the direction of the movement; otherwise, you take the component in that direction. Result is in Newton-meter, also called Joule.In this case, you simply multiply the force times the distance.

What is work equal too?
Work Done= Force x Distance , where the unit of work is Joules and 1 Joule= 1 Newton-meter.
What amount of work is done on a cart that is pushed 4 meter across a floor by a horizontal 50 Newton net force?
Work= 200 Joules.
It took a 500 newtons ballerina a force of 250 joules to lift herself upward through the air. How high did she jump?
um.. 7?
What does a high newton meter reading mean?
Unfortunately, you'll have to be more specific. If you are referring to a Newton meter (instrument), a high meter reading would indicate a high force or weight (not mass). Alternatively, a Newton-meter could be a Joules (a unit of work) or, if the force is applied as a rotational force, a Newton meter would be a unit of torque.
What ia a force meter measured in?
usually in joules or lb/ft
You applied 50 newton force to a box but it did not move he applied 2 newton force to an apple and moved it 1 meter who did more work?
Technically, the force does no work unless it acts through a distance. Since the box didn't move,no work was involved there.Concerning the apple, the work done there was (2N x 1m) = 2 newton-meters = 2 joules.
Would a nine meter force applied 2 meter from the fulcrum lift the weight?
No sweat. Piece o' cake. Bring it on! What's a "nine meter force" ? ?

How much work is needed for a 30 meter by 5 meter ramp with 200 newtons of force needed to push a 1000 newton piano?
5000 joules
What does joules mean science?
It is the unit of energy. 1 joules is quantified to energy equivalent to force of 1 Newton act on any object over the length of 1 meter.
How much energy can be created from a generator with 100 pounds of force?
The technically correct answer is none. no energy will be created or destroyed, only converted from one type to another. Kinetic energy from a 100 lbs force can be transformed into electrical energy using a generator, however. 100 lbs of force is equivalent to ~445 Newtons, or 445 Joules/meter. So, if a 100lbs force is applied over 1 meter to a generator, it can, at most, produce 445 joules of electricity. The actual produced energy will depend on the efficiency of the generator, and any other losses between the measurement of the 100 lbs of force to the generator. 1 Joule is equivalent to 1 watt second. 445 joules is equivalent to 445 watt seconds, or ~124 milliwatt hours (if you want to relate it to your electric meter).
Who created the force-meter?
Robert Hooke created a force meter in 1678. It showed how the distance a spring will stretch is proportional to the amount of force applied to it. His theory is known as Hooke's Law.

How many thunderstorms can occur at any given time?
That is why both work and energy are measured in Joules. To do the work I applied a force (equal to the weight of the book) to the book from the floor to the tabletop.Workequals the force times the distance, in units of Newtons times Meters. Therefore 1 Newton-Meter (NM) equals 1 Joule.
