If it took 5 seconds to lift the crate using a machine what was the power rating of the machine?
We have no way of knowing what power the machine was rated for, but with the information given in the question, we can calculate the power it delivered during the crate-lift: It was (1.96) x (mass of the crate in kilograms) x (distance the crate was lifted in meters) watts.
A machine lifts a load of 240-kilograms a distance of 120-meters in 45-seconds. How much power is generated by the machine?
If you multiply the weight (mass x gravity) by the height, you get the energy required. (Note: gravity is about 9.8 newton / kilogram.) You then need to divide that by the time, to get the power.
A 25 gram is lifted to a height of 5 meters. How much potential energy does it have?
PE = m g H = (0.025) (9.8) (5) = 1.225 joule
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?
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
If a 50 crate was lifted to a height of 10 meters and it took 5 seconds to lift the crate using a machine what was the power rating of the machine?
Please use the formula for gravitational potential energy (PE = mgh) to calculate the energy required. Then divide that by the time to get the power.
A machine lifted a 1000 n object 40 meters in 15 seconds how much work is done by the machine?
work = f x s. work = 1000 x 40 40000J

1-kg brick is lifted to a height of 30 meters and then dropped How much potential energy remains after 2 seconds of freefall?
Use one of the formulas for constant acceleration to calculate how many meters the brick will fall after 2 seconds. Subtract this from the 30 meters, to see how high the brick is above ground. Finally, use the formula for potential energy: PE = mgh, to calculate the potential energy.
A 10 KG mass is lifted to a height of meters what is its weight?
To get the weight (in Newton), multiply the mass by Earth's gravitation - about 9.8, in SI units.

How much work is done when an object with a mass of 78 kilograms is lifted through a height of 6 meters?
78*6*9.8 N = 4586.4 N
How much work is done by gravity as the riders are lifted to a height of 60 meters?
Gravity does not lift. The force is doing the work by lifting the riders. When the riders come down from the 60 meter height, then gravity will be at work.
