1.The coefficient of static friction between a 10 kg object and the floor is 0.50. What is the force of static friction between the object and the ground if someone tried to push it?

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.

conservation of mass

mass before something happens = mass afterwards
