Use the formula potential energy = mgh (mass x gravity x height), mass in kilograms, gravity about 9.8 (meters per square second), height in meters. Answer will be in Joules.

How much work is needed to move a 280 N shed to a platform 5 m above?
1400 Newton-meters = 1400 joules
How much work will be needed to lift a block weighin 4 newtons and a distance of 10 meters?
Work = force x distance = (4 x 10) = 40 newton-meters = 40 joules
How much work is being done to raise a 5kg stone 1 m off the ground?
The force needed to lift the stone is (M G) = (5 x 9.8) = 49 newtonsWork = (force) x (distance) = (49 x 1) = 49 newton-meters = 49 joules
How much energy is needed in Joules for a 90 kg woman was to climb a ladder 6 meters in height?
The energy needed for a woman to climb a ladder is given by the change in potential energy she experiences. Defining the ground as being zero potential energy, her overall change in potential energy isEp = mghwhere Ep is the change potential energy, m is her mass, g is the gravitational acceleration (9.8m/s2 on earth) and h is the height she climbs.Ep = (90kg)(9.8m/s2)(6m) = 5292kg*m2/s2 or 5292 Joules
The amount of force needed to lift a petrified log is 5000 N How much work is required to lift the log 5 meters?
Work is expressed in Joules, or a Newton meter. So to lift the log five meters would take 25 kiloJoules.
How many Joules of work are needed to climb a 35 kilogram tree 27 meters off of the ground?
The question includes information that we don't need, and leaves out informationthat we do need.It doesn't matter at all what the mass of the tree is, but in order to answer the question,we do need to know the mass of the person climbing it.
How much energy is needed to move an electron in a hydrogen atom from the ground state n equals 1 to n equals 3 in joules?

How much work will be needed to lift a block weighin 4 newtons and a distance of 10 meters?
Work = force x distance = (4 x 10) = 40 newton-meters = 40 joules
160j ofwok was needed in order to move an object 8m across a floor What was the force in n that as needed to do this job?
I'm assuming you mean 160 Joules of work.What you need to know for any work questions like this is the formulaWork=Force times DistanceORW=F*DSo in this problem, you're given the Work (160 Joules) and the Distance (8 meters) and you need to find force.Plugging it into the equation:160 Joules= F *(8 Meters)Solving for FF=160 Joules/8 MetersF= 20 Joules/MeterTurns out you're lucky.. 1 Joule/Meter =1 NSo your final answer isF=20N
Calculate the work needed to push 50 newton box to a distance of 3 meters?
the answer for this question is 150 nt-m or 150 joules....................why is this my answer, how did i get this?work= newton box X distance (changed into meters)nt-m means joules or the amount of work neededthis is from mrs. macapundag's pupilfor the pshs reviewer 2
