Question

The graph represents the height y, in meters, above the ground of a water balloon x seconds after it is dropped from a window.

Which statements are true?

Select each correct answer. (MULTIPLE ANSWERS)

The maximum height of the water balloon occurs at x = 0.

The water balloon hits the ground in 44 s.

The water balloon travels at 3 m/s .

The water balloon rises above 44 m before falling toward the ground.

The maximum height of the water balloon is 44 m.

The water balloon is in the air for 3 s.

Answer 1

i)The maximum height of the water balloon occurs at x = 0.

iii) The water balloon travels at 3 m/s .

v)The maximum height of the water balloon is 44 m.

vi)The water balloon is in the air for 3 s.

Explanation:

We are given the graph that represents height of a water balloon.

In the given graph, the x-axis represents the time (s) and the y-axis represents the height(m) of the ball.

From the given graph, we can interpret the following information.

i) when s = 0, the height of the ball is 44 meter which is the maximum height of the ball.

ii) when s = 3, the ball reaches the ground.

iii) The ball in the air from s = 0 to 3 seconds.

Therefore, the following statements are true:

i) The maximum height of the water balloon occurs at x = 0.

iii) The water balloon travels at 3 m/s .

v)The maximum height of the water balloon is 44 m.

vi)The water balloon is in the air for 3 s.
