A weight attached to the end of a long spring is bouncing up and down. As it bounces, its distance from the floor varies sinusoidally with time. You start a stopwatch. When the stopwatch reads 1.7 seconds the spring is 58 cm above the floor and is on a downward path. It takes 4.4 seconds for the spring to bounce from a distance of 36 cm to 80 cm above the ground.
A. Write an equation expressing distance from the floor in terms of the number of seconds the stopwatch reads
B. Predict the distance from the floor when the stopwatch reads 6 seconds
C. What was the distance from the floor when you started the stopwatch?
