Question

The second floor of a house is 6 m above the street level. How much work is required to lift a 350-kg refrigerator to the second-story level?

science physics

Answer 1

Answer #1

Using work-energy theorem ( work done is equal to change in the potential energy or change in the kinetic energy )

So

....1

Here m=350 kg , h=6 m , g=9.80 m/s²

Put these value in equation 1
