It's for extra credit and i need suppose an 85 kg sky diver is falling toward the earth. when the skydiver is 25 m above the earth, he is moving 55m/s. at this point, calculate the sky divers gravitational potential energy. about 46,000 jabout 21,000 jabout 128,600jabout 116,900j

about 21,000 J

Explanation:

The skydiver gravitational potential energy is given by

where

m = 85 kg is the mass of the skydiver

g = 9.81 m/s^2 is the gravitational acceleration

h = 25 m is the height above the ground

Substituting the numbers inside the formula, we find

which is approximately 21,000 J.

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

0.19 m/s and 0.45 m/s
