Two astronauts, each having a mass of 65.5 kg, are connected by a 12 m rope of negligible mass. They are isolated in space, orbiting their center of mass at speeds of 5.13 m/s. Calculate the magnitude of the initial angular momentum of the system by treating the astronauts as particles

Explanation:

Formula to calculate the angular momentum is as follows.

                L = mvr

where,   m = 65.5 kg

              v = 5.13 m/s

               r = 12 m

Therefore, calculate the angular momentum as follows.

                L = mvr

                   =

                    = 4032.18

Therefore, we can conclude that the magnitude of the initial angular momentum of the system by treating the astronauts as particles is 4032.18 .

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.
