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?

1 sec, 0.5 sec, 1.5 sec

What reasonable assumption did you make to arrive at your

answers?

2 sec from point a to eqil to point b back to eqil and then to a

0.5 sec from point a to equil and 0.5 from eqil to point b so 1

sec total

0.5 sec from point a to eqil

0.5 sec from point a to eqil and 0.5 sec to point b and 0.5 sec

from point b to eqil so 1.5 sec total
