GIVING BRAINLIEST! PLS HELP! A pendulum is swinging back and forth. At t = 0, the pendulum is hanging straight. It takes 4 seconds
for the pendulum to swing all the way to the right, back through its middle position, all the way to the
left, and back to its starting position.
The maximum horizontal distance the pendulum reaches from its initial position is 3cm. Plot the
horizontal displacement of the pendulum as a function of time. Show three cycles on your diagram.
Use these questions to guide you:
a) What are the independent and dependent variables? Add these to your axes.

b) What is the amplitude (a) of this function?

c) What is the period (T) of this function?

d) At what time will the pendulum have zero horizontal displacement? (ie. it is at its initial position)?

e) At what times will it be all the way to the right?

f) At what times will it be all the way to the left?
