Aperson throws a ball straight up in the air. the ball rises to a maximum height and then falls back down so that the person catches it. consider the ball while it is in the air. which of the following statements are true? just after the ball leaves the person's hand the direction of the acceleration is up. the acceleration is zero when the ball reaches its maximum height. the acceleration is about 9.8 m/s2 (down) when the ball is falling.

The acceleration is about 9.8 m/s2 (down) when the ball is falling.

Explanation:

The ball at maximum height has velocity zero

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration due to gravity = 9.8 m/s² (positive downward and negative upward)

The accleration 9.8 m/s² will always be acting on the body in opposite direction when the body is going up and in the same direction when the body is going down. The acceleration on the body will never be zero

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
