Answer:
E = 225.4 J
Explanation:
Given that,
The mass of a brick, m = 2 kg
It is lifted up by 11.5 m
We need to find the gain in gravitational potential energy. The formula for gravitational potential energy is given by :
[tex]E=mgh\\\\E=2\times 9.8\times 11.5\\\\E=225.4\ J[/tex]
So, the gain in gravitational potential energy is 225.4 J.
