. A disk slides toward a motionless stick on a frictionless surface.

b. The disk hits the stick at one end and adheres to it, and they rotate together, pivoting around the nail.

Suppose the disk in the picture above has a mass of 50.0g and an initial velocity of 30.0ms when it strikes the stick that is 1.20m long and 2.00kg at a point 1.00m from the pivot. What is the angular velocity (in rads ) of the two after the collision?

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

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: )
