Question: Sarah grandpa has a pendulum Clock which swings in a periodic motion. When it’s at rest, it’s 12cm off the base. The highest point of the swing is 18 cm above the base, and takes about 4 seconds for the pendulum to swing back and forth to its starting point once. Part 1: Write a sine equation for the height of the pendulum. Part 2: At 4.5 seconds, how much above the base is the pendulum?
( must be in teh form of (h(t)=asin[k(x-d)]+c )
