A baseball player throws a ball giving it a change in momentum of 6.5 (kg•m)/s over 90 ms.
What is the magnitude of the net force on the ball?

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.

the inner core.

good luck: )
