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. (Ignore gravity and assume the spring keeps moving.) You start a stopwatch. When the stopwatch reads 0.3s, the weight first reaches a high point 60 cm above the floor. The next low point, 40 cm above the floor, occurs at 1.8s. a. Sketch a graph b. Identify the key features Amplitude: Midline: Phase Shift: Period: Frequency: c. Create an equation to model this scenario d. How high above the floor is the weight at 17.2s? e. What was the distance from the floor when you started the stopwatch? f. Predict the first positive value of time at which the weight is 40 cm above the floor
