Calculate the work done in lifting a 500-N barbell 2.2m above the floor what is the potential energy of the barbell when it is lifted to this height?

Work = Force x distance
So since the barbell is 500N and the barbell travels 2.2 meters it becomes
500N x 2.2m = 1100 joules (N x m)

What is the potential energy of the barbell when it is lifted?
The potential energy increases because of the weightlifter lifting it above his head (Hope this helps)XP
Is lifting weight kinetic or potential energy?
potential because it is storing its energy
When lifting the tank of water gave it what energy?
Gravitational potential energy.
Work done in lifting and lowering an object?
potential energy
When you lift an object energy is transferred to an object which gives the object?
When you lift an object, the energy transferred to the object is called gravitational potential energy.

Why did one barbell have potential energy while the other did not?
it was anger

How do you calculate energy input for lifting objects by weight and height lifted?
When an object is lifted to a certain height, the mechanical energy of the person or system lifting the object gets transferred into the potential energy of the object. Thus if an object of mass/weight 'm' is lifted to a height 'h', then the potential energy possed by the object at height 'h' is given as: Potential Energy (P.E)= m*g*h, where g is acceleration due to gravity and whose value is 9.8 m/s2.
What forms of energy are used when someone lifts a barbell to momentary muscular failure?
I don't know what you mean by momentary muscular failure. Surely if this happens he won't succeed in lifting the barbell? Lifting a barbell or indeed any muscular work done involves chemical changes in the muscles which provide the energy required, in this case raising the weight against the force of gravity. The energy used to lift a weight m kg a height of h meters is 9.81 x m x h joules.
What is the mechanical output power while lifting a 300 gram mass 60 centimeters?
Not enough information. You can calculate the work (using the formula for potential energy), but to calculate the power, you would also need the time (how fast is this done?)
When you lift an object energy is transferred to an object which gives the object?
When you lift an object, the energy transferred to the object is called gravitational potential energy.
How do you calculate an objects mechanical energy?
An object's mechanical energy is the sum of the potential and kinetic energy it possesses.
What does Lifting an ax higher when chopping wood adds to the of the ax?
potential mechanical energy
What type of energy is present in a barbell lifted or a shot-pull being thrown?
kinetic energy being enacted. this energy is giving rise to potential energy too, as the item is being lifted into the air. When an item is lifted, it is given potential energy, as this potential energy is what fuels its future descent. So, when moved, kinetic energy is both moving the object, and storing potential energy for future use.
