50 lbs is equivalent to approximately 22.68 kilograms.
Energy(weight)
The work done to lift the box can be calculated using the formula: work = force x distance. The force required would be equal to the weight of the box, which is the mass of the box multiplied by gravity (9.8 m/s^2). The distance is given as 0.5 meters. Calculate the force needed to lift the box (mass x gravity), then multiply it by the distance to get the work done in Joules.
The work done to lift the 5-kg box to a height of 1 meter would be 49.05 Joules (work = force Γ distance). In this case, the force required to lift the box against gravity can be calculated as force = mass Γ gravity, which is force = 5 kg Γ 9.81 m/s^2.
The work done to lift the box is equal to the force applied multiplied by the distance moved, which is 20 joules in this case (10 N * 2 m). Power is the rate at which work is done, so if the box is lifted in 1 second, the power required would be 20 watts (20 joules / 1 second).
This depends on if you were lifting things from day one. If you are use to say lifting 50lbs at a time then lifting 50lbs will not bother you nor the baby at 5months. But if you do not do any lifting, then it isn't a good idea to up and start lifting things that are heavy. Most doctors would say not to lift over 20lbs. That is about the weight of a toddler.
It depends upon your strength and conditioning, as well as the configuration of the object to be lifted.
50lbs is 22,679.6 grams.
Impossible to answer. The answer depends on the density of whatever is in the bag. e.g. a 50lbs bag of feathers would take up a large amount of space (and contain a larger number of gallons) while a 50lbs bag of lead would be significantly smaller (and contain a fewer number of gallons).
Get someone to help you lift it.
it would be approximately 4,535 nickels and at a total price of 226$.
As both have the same weight of 50lb, so are equal in weight.
50 lbs is equivalent to approximately 22.68 kilograms.
No work is being done. Work is when an object moves in the same direction as the force applied to it.
