HELP!! An illustration of a pendulum at 3 positions of a pendulum. The equilibrium position is labeled B. The other two position
s are the maximum displacement of the pendulum labeled A and C. In between A and B are 3 lighter colored pendulum sketches equally spaced. In between B and C are 3 lighter colored pendulum sketches equally spaced.
At which point(s) does the pendulum have the greatest potential energy?
A only
B only
C only
both A and C

Explanation:
Given
mass of clock 93 kg
Initial force required to move it 610 N
After clock sets in motion it requires a force of 514 N to keep moving it with a constant velocity
Initially static friction is acting which is more than kinetic friction
thus 613 force is required to overcome static friction
