An object is dropped from rest from a height 5.6 × 106 m above the surface of the earth. if there is no air resistance, what is its speed when it strikes the earth? the acceleration of gravity is 9.81 m/s 2 and the radius of the earth is 6.37 × 106 m. answer in units of km/s.

The answer to your question is:  10.48 km/s

Explanation:

Data

h = 5.6 x 10⁶ m

g = 9.8 m/s²

Formula

                 vf =

Substitution

                vf =

                vf =

                vf = 10476.64 m/s

convert to km/s

               vf = 10476.64/1000

               vf = 10.48 km/s

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

i believe the answer is electric potential.
