7. A man has a mass of 80 kg on Earth. 7 a. What is the man's weight on Earth in Newtons? What is the
man's weight on Earth in pounds?

7 b. What is the man's weight on Mars where the acceleration
due to gravity is 3.7 M/ky? Show your answer in both
Newtons and pounds.

7c. What is the man's mass while on Mars? Explain your answer.

explanation:

the masses of the objects and the distance between them

grav force prop 1/r squared 2r all squared is 4rsquared 1/4rsquared quartered

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

denser than water sinks in water.

denser than mercury would sink in it
