To find the average power delivered by the gravitational force at the point where the object reaches half of its maximum height, we need to follow these steps:

Find the maximum height reached by the object

 

The object is thrown vertically upward with an initial speed . At the maximum height, the final velocity will be 0 m/s. We can use the following kinematic equation to find the maximum height:

Where:

(at maximum height),

,

(acceleration due to gravity),

is the maximum height.

 

Substitute the values:

So, the maximum height is 5 meters.

 

Find the height where the object reaches half of its maximum height

At half of the maximum height:

 

Calculate the velocity at half of the maximum height

We can use the kinematic equation to calculate the velocity at the height of :

Substituting the values:
