Group - 'C'[4x3=121 12. How much energy is stored when a mass of 70kg is lifted upto
the height of 30m?​

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.
