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 much work is required to lift a 360 kilogram piano to a window whose height is 10 meters from the ground?

We could actually solve that if we knew ==> the weight of the piano,and ==> the distance between floors.The power is:[ (weight of the piano in newtons) x (distance between floors in meters) / 10 ] watts.


What is the amount of force required to lift an object against the force of gravity equal to?

The acceleration due to gravity (9.8 meters/sec.^2) * mass of object.


How much force to lift 50 kilograms onto a shelf 3 meters high?

The height is irrelevant. The energy required depends on the height; the force does not. The weight of an object, and therefore the force required to lift it, is mass x gravity - about 500 Newtons.The height is irrelevant. The energy required depends on the height; the force does not.

A forklift picks up a crate using 400 N It moves the crate 20 meters in 50 seconds How much power is used?

From the question, it's hard to tell whether the 20 meters is the vertical lift, or a horizontal transfer that occurs after the lift.If the 20 meters is the vertical lift (performed by a very large fork-lift in a shop with a very high ceiling):Energy = work = 400 N times 20 m = 8,000 Newton-meters = 8,000 joules8,000 joules in 50 seconds = 8,000 / 50 = 160 joules per second = 160 watts = about 0.214 horsepower.If the 20 meters is a horizontal ride after the lift is complete, then that part of the move consumes nominally no energy or power. No force is required to move an object perpendicular to the force of gravity. Whatever force is applied initially, to get the crate moving, is returned at the end of the 20 meters, when reverse force must be applied to the crate in order to make it stop moving.

If it takes 3400J to lift a rock onto a ledge what power is required to lift the rock onto the ledge in 4 seconds?

If it takes 3400J to lift a rock onto a ledge, what power is required to lift the rock onto the ledge in 4 seconds Power is energy per unit time. It is measured in watts (joules per second). As such if 3400 joules is transfeered in 4 seconds, the power equals 3400 / 4. The power required is therefore 850 watts.


How much hydrogen gas required to lift 1kg weight?

I believe it is approximately 1.13 cubic meters (1.13 litres will lift 1 gram; do the math.


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.


How much power is used if the 950 N person lifted 3 meters?

To lift a 950-N load 3 meters requires (950 x 3) = 2,850 joules of energy.The power is the rate at which the energy is delivered. It takes more powerto lift the load faster.The power used to lift this load is (2,850 joules) divided by (the number of seconds it takes),and the unit of the answer is watts.


What is the power rating of a machine to lift a crate in 5 seconds?

That really depends on the weight of the crate. Also, on how high you want to lift it. Calculate the energy required to lift the crate with the formula for gravitational potential energy: PE = mgh (mass x gravity x height) Then divide this by the 5 seconds to get the minimum power required. (The actual power is somewhat larger, for various reasons - the initial acceleration required, and losses due to friction.)

What is the minimum wattage rating for a motor that is required to lift a 1000 N load a vertical distance of 4 meters in 2 seconds or less?

1 watt = 1 joule/sec; 1 joule = 1 N*m (Newton * meter) 1000 N * 4 m / 2 sec = 2000 N*M/sec = 2000 watts But this is just the power to lift the load and does not take into account any friction or the power required to create the magnetic field in the windings.


How much power is required to lift a 2.0 kg mass at a speed of 2.0 ms?

How many watts of motor are required for 30 kg material?

If it's to lift 30 kg, it depends how far it is to be lifted and how quickly the lift takes to complete. To lift 30 kg through 10 metres requires 30 x 9.8 x 10 joules of energy, that is 3000 Joules. To do that in 10 seconds needs 300 watts, which would be about half a horse power motor. To do it in 5 seconds the power would be 600 watts - a 1 horse power motor.


What is the amount of force required to lift an object against the force of gravity equal to?
