A uniform meter stick supported at the 25-cm mark is in equilibrium when a 1 -kg rock is suspended at the 0-cm end (as shown in Fig. 9-37). Is the mass of the meter stick greater than, equal to, or less than the mass of the rock? Explain your reasoning.
Step 1 of 1
The weight of the hanging rock.
The weight of the meter stick.
The stick is in equilibrium, so we can write the second condition of equilibrium
