Answer:
E = 20580 J
Explanation:
Given that,
Mass of the object, m = 70 kg
It is lifted upto the height of 30 m
We need to find the energy stored when the mass is lifted. We know that, the energy stored by the object is given by :
E = mgh
Put all the values,
E = 70 kg × 9.8 m/s² × 30 m
E = 20580 J
So, 20580 J of energy is stored in the object.
