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.

Statement B)

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.

Statement C)

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.

Statement D)

False

The ball travel 3cm in 0.5s.

Ibelieve the answer your looking for is d.

Ok here we go ..there are plenty of ways to solve such math problems but we will go for the smartest and easiest ..5x+2y=7  -2x+6y=9we rearrange them into the following ..by multiplying the 1st equation by 2 it becomes 10x + 4y = 14we rearrange it and so it becomes 10x = 14 - 4yas for the second equation we multiply it by 5 and rearrange it so it becomes as to the following ..-10x + 30y = 45rearranging so 10x = 30y -45now 10x equals both 14 - 4y and 30y -45so   14 - 4y = 30y -4531 = 26yy= 31/26 = 1.19 or around 1.2so by now we can calculate x easily as  -2x+6y=9so 2x = 6y -9 = 6 * 31/26 - 9 = -1.84  then x = - 0.92 or around -0.9best luck!
