2) 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 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.
b)
d)
Sketch a graph.
Write an equation expressing distance from the floor in terms of the number of
seconds the stopwatch reads.
Predict the distance from the floor when the stopwatch reads 17.2 s. 43.309 cm
What was the distance from the floor when you started the stopwatch?
Predict the first positive value of time at which the weight is 59 cm above the floor.
