50 POINTS !! Antoine pulls a weight attached to a spring below its resting, or equilibrium, position. When Antoine releases the weight, it oscillates above and below its equilibrium position as shown in the table. The displacement of the weight from its equilibrium position, , in centimeters, is modeled by a cosine function, where t represents time, in seconds. At which interval is the weight above its resting position?

The amplitude A of the wave is the maximum displacement of the wave from the equilibrium position, which is indicated by the dotted line. In this example, the medium moves up and down, whereas the disturbance of the surface propagates parallel to the surface at a speed v. v=λT=λf.

where's the diagram?

step-by-step explanation:

answer: 30

step-by-step explanation: its 30 because im a basketball player and stephen curry hits most of his shots so if you put 30 you might make the shot goodluck
