In the diagram below, which of the following represents the equilibrium? diagram of wave. the distance from the top of one wave to the top of the next wave is labeled 'a.' the high point of each wave is labeled 'b.' the low point of each wave is labeled 'c.' the midway point between 'b' and 'c' is labeled 'd.' a b c d

The answer is D.

A is the wavelength. As it says in its title, it shows the length of one complete wave.

B is the crest. This is the point in the wave where it's at its highest.

C is the trough. This is the point in the wave where it's at it's lowest.

And lastly, D is the equilibrium position. These are the points on the wave where they touch the equilibrium, or the horizontal line going through the wave.

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
