A pendulum requires 2 seconds to complete a cycle, which consists of a complete back-and-forth oscillation (extreme point to equilibrium to opposite extreme point back to equilibrium and finally to the original extreme point). As long as the amplitude of the motion (the amplitude is the distance from the equilibrium position to the extreme point) is small compared to the length of the pendulum, the time required for a cycle is independent of the amplitude.
• How long does it take to get from one extreme point to the other, how long from an extreme point to equilibrium, and how long to go from extreme point to equilibrium to opposite extreme point and back to equilibrium?
To get from one extreme point to another, it would take 1 second. From one extreme point to the equilibrium, I would assume that it takes 0.5 seconds. From one extreme point to the other and back to the equilibrium, I would assume that it takes 1.5 seconds.

• What reasonable assumption did you make to arrive at your answers?
I made the assumption that the pendulum is symmetrical about the equilibrium. This means that if it took 2 seconds to go through one whole cycle, then it would take 1 second to go through half a cycle. If you look at it proportionally, the answer to the above questions is easily found.
