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?

a. the ball travels 12 cm in 2 s.

b. the amplitude is 6 cm.

c. the ball travels from its highest point to its lowest point in 1 s.

d. the ball travels 3 cm in 0.75 s.

a) , c)

Step-by-step explanation:

Statement A)

From 0.25s to 0.75s

the ball has travelled 3cm

From 0.75s to 1.25s

the ball has travelled 3cm

This means that in 1 second ball has covered 6 cm so in 2 sec it will cover 12 cm.

False

The amplitude of the oscillation is the maximum distance of the object either in positive y axis or negative y axis.

so its is 3 cm.

At 0.75s

Ball is at its highest point

At 1.75

Ball is at its lowest point

so in 1 second the ball travels from its highest point to its lowest point.

False

The ball travel 3cm in 0.5s.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
