An initially stationary device lying on a frictionless floor explodes two pieces, which then slide across the floor, one of them in the positive x direction. a) What is the sum of the momenta of the two pieces after the explosion? b) Can the second piece move at an angle to the 3 axis? c) What is the direction of the momentum of the second piece?

b.

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.
