<h3><u>Answer:-</u></h3>
1115.2 Joules
<h3><u>Given :- </u></h3>






<h3><u>Solution</u> :-</h3>
As the block falls , the change in potential energy will be converted into kinetic energy
Potential Energy at rest at height,
=
Potential Energy when fell at height,
=

Kinetic energy= Change in Potential energy = =





Explanation:
Given that,
Mass if the rock, m = 1 kg
It is suspended from the tip of a horizontal meter stick at the 0-cm mark so that the meter stick barely balances like a seesaw when its fulcrum is at the 12.5-cm mark.
We need to find the mass of the meter stick. The force acting by the stone is
F = 1 × 9.8 = 9.8 N
Let W be the weight of the meter stick. If the net torque is zero on the stick then the stick does not move and it remains in equilibrium condition. So, taking torque about the pivot.

W = 3.266 N
The mass of the meters stick is :

So, the mass of the meter stick is 0.333 kg.
