Apiece of spacecraft debris initially at rest falls to the earth's surface from a height above the earth equal to one-half of the earth's radius. find the speed at which the piece of debris hits the surface. neglect air resistance and the gravitational pull of the moon.

Explanation:

As per given conditions we neglect the the air resistance and gravitational pull by the moon.

Height of fall of debris, (half of earth's radius)

Since the object is under free fall, it will go through the acceleration and will finally impact the ground with a velocity given by:

the assestment will probley apele with cause and effect

the closer the planet is to the sun, the larger the gravity
