The graph shows the vertical position of a ball attached to a spring oscillating between a low point and a high point as a function of time.
Select all statements that describe the graph.
The ball travels 12 cm in 2 s.
The ball travels 3 cm in 0.75 s.
The amplitude is 6 cm.
The ball travels from its highest point to its lowest point in 1 s.
Look at the graph:
at 0.25 to 2.25 (2 seconds)
the ball travels up 3 cm then down 3cm then down 3cm more then back up 3 cm = 12 cm
From 0.25 s to 1 sec is 0.75 sec .....the ball travels up 3cm and begins to travel down.....a total of more than 3 cm
Amplitude is height from the midline ....or total height / 2 = 3 cm
From highest point at 0.75 sec to lowest point at 1.75 sec IS 1 second....
