Use the formula for potential energy: PE = mgh (mass x gravity x height). Since you are using SI units, use 9.8 for gravity.

How do you convert from mass to distance?
With extreme difficultly as they measure different things: mass is a measure of how much something weighs*, whereas length is a measure of distance. * Actually weight is the force on a mass due to acceleration and is measured in Newtons. However, weight and mass are often, incorrectly, used interchangeably and I cannot think of a better word to describe mass. To further muddy the waters, mass and distance ARE related by energy and acceleration: energy = (mass × acceleration) × distance which can be rearranged to distance = energy ÷ (mass × acceleration) So for an object given a mass, an acceleration (on earth acceleration due to gravity is a good one) and an amount of energy put in, the distance the object is moved (by that energy [in acting as a force]) can be calculated.
If you want to lift a 30-kg box to a height of 1 m how much work will it take?
29
How much work is done when a mass weighing 350 N is lifted 4 meters?
1400j
How much work is done to lift a 50 kg object 4 meters?
Weight of a mass of 50 kg = [ m g ] = (50 x 9.8) = 490 newtons.Work = force x distance = 490 x 4 = 1,960 newton meters = 1,960 joules
How much does 1 gram equal in centimeters?
Grams and centimeters are not equivalent units and there is no conversion. The gram is a unit of mass, and a centimeter is a unit of distance.
How much work is done in lifting a 600kg sack of rice to a vertical distance of 10m?
Just use the formula for gravitational potential energy:GPE = mgh Where m is the mass, g the gravity (around 9.8, in SI units), and h the height.
How much work is done when a 700 N refrigerator is lifted straight up a distance of 4 meters in joules?
Work is done in lifting is equal to work done in opposing gravity. Work done in opposing gravity = weight times distance = 700 x 4 =2800 joules
How much force exert when lifting an object?
a force of depend on mass
If you lift two loads up one story how much work do you do compared to lifting just one load up one story?
The work done by lifting two loads up one story vs the work done lifting one load will depend on the weight of the second load. If it is the same as the first load, it would simply be twice the work to lift. Work is described as a force times a distance and a force is described as a mass times an acceleration. In this case, the force would be twice as much, so the work would be as well.
How much work is done in lifting a 20 kg object through a distance of 0.40 m Use g 10 ms?
Work Done= Force X Distance moved by the object in the direction of the force = 20kg X 10N/kg X 0.40m = 80J
How much work is done in lifting a 50kg object to height of 5m?
anser
How much work is done lifting a 9.10-kg box straight up onto a shelf that is 1.80 m high?
9.10 * 1.80
How much is 10 milimeters in mass?
A millimetre is a unit of distance, not mass. Therefore, it is inconvertible to a unit of mass.
How do you determine how much work is done?
First you have to find the force F=(mass/weight of object)*(9.8) Once you find force Work=(Force)*(Distance) Your answer will be in joules
How much work is done in lifting a 300-lb load of bricks to a height of 60 feet on a building under construction?
Work = (force) x (distance) (300 poundforce) x (60-ft) = 18,000 foot-pounds
Who much work needs to be done to lift a 500kg mass from the ground to a height of 20 meters?
work=force(distance) work=500(20) work=10000 joules
An object with a mass of 21 kg is lifted through a distance of 7 meters how much work is done?
Work = (force) x (distance) = 7 x 2.4 = 16.8 joules
