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.

How many joules of work are needed to life a 15 kilogram mass 3 meters off the ground?

Use the formula potential energy = mgh (mass x gravity x height), mass in kilograms, gravity about 9.8 (meters per square second), height in meters. Answer will be in Joules.


When the flower pot in problem 3 is only 10 meters from the ground what is its potential energy?

I think we have the same question, Potential Energy = Weight X Height. It weighs 3 Newtons and is 10 meters from the ground. 3*10=30. I am pretty sure the answer is: 30J


What is the potential energy of a kilograms person that is W meters above ground?

The potential energy of a person standing W meters above the ground can be calculated using the formula: Potential energy = mass x gravity x height, where mass is in kilograms, gravity is approximately 9.8 m/s^2, and height is in meters.


How much work does a crane do as it lifts a 240 kilogram crate from ground level to a height of 165 meters?

The work done by a crane lifting a 240 kg crate to a height of 165 meters is equal to the change in potential energy of the crate. The work done can be calculated using the formula: Work = force x distance. In this case, the force is equal to the weight of the crate (240 kg x 9.8 m/s^2) and the distance is 165 meters.


How much work is done if a fallen tree is lifted 2.75 meters?

The work done in lifting the tree is equal to the force applied multiplied by the distance it is lifted. The amount of work done would depend on the weight of the tree and the force required to lift it to a height of 2.75 meters above the ground.

What is the maximum height a 3-kilogram rock will reach if it has a maximum of 400 joules of potential energy during a toss?

Gravitational potential energy relative to the ground =(mass) x (gravity) x (height above ground).Height = (PE)/(M x G)= 400/(3 x 9.8) = 13.6 meters (rounded)Now that we have all the figures, it would be interestingto speculate on whether there's anybody who could tossa 6.6-pound rock to 47 feet off the ground !
