use the formula W = mgs
W stands for work done in joules
m stands for mass of the object
g stands for gravity
s stands for the distance the object is lifted
W = mgs
W = 78kilograms•9.8m/s2•6meters
W = 4586.4 J (joules) answer would be 4,586.4 J

∙ 13y agoit is impossible to know you have to give a velocity to get its momentum otherwise you cannot determine this answer.

An object with a mass of 21 kilograms is lifted through a distance of 7 meters How much?
question 24 on penn foster is C.
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
An object of mass 4.5 is lifted through a distance of 10m H ow much work is done?
I believe that when you say 'lifted through', you mean lifted to a height of 10m. If so, the amount of work is such: Work= Force x Distance which have the units (Joules = Newtons x meters) When the object is lifted, it increases in its potential energy. The equation for this is: Potential energy = mass x gravitational force x height = 4.5 x 9.81 x 10 =441.45 Joules As 1 joule = 1 newton x meters and we have 441.45 Joules, 441.45 joules of works is done! :D
What is the potential energy of a crate lifted with a force of 100 newtons a vertical distance of 2 meters?
Force x distance = 100 x 2 = 200 newton-meters = 200 joules.
How much work is done when 700 n object is lifted straight up a distance of 4 meters?
700 x 4 = 2,800 newton-meters = 2,800 joules
How many joules of work are done when a 20 newton is lifted 5 meters off of the floor?
The idea here is to multiply the force by the distance.
What is the answer if A fallen tree is lifted 2.75 meters How much work is done?
a fallen treee is lifted 2.75 meters. How much work is done?
How much work is done when 700 n refrigerator is lifted straight up a distance of 4 meters?
Work = Force x distance = 700N x 4m = 2800N•m = 2800 Joules
How much work is done when a ball weighing 20 Newtons is lifted a vertical distance of 2 meter?
Work = force x distance = 20 x 2 = 40 newton-meters = 40 joules
How many joules of work is being done when a 700 newton refrigerator is lifted straight up a distance of 4 meters?
Work is force x distance = 700 x 4 = 2800 Joules
How much work is done when a 700 N refrigerator is lifted straight up a distance of 4 meters?
Work = Force (N) x Distance (m) Therefore, the units of work are N-m, or Newton-meters. F=700N D=4m W=FxD = 700x4 = 2800N-m
How much work is being done if a 100 N box is lifted meters off the ground?
If a 100 N box is lifted 3 meters off the ground, the answer is 300 joules.
