A 10 kg disk with a hole in its center has a c value about its center of 0.56 has an outer radius of 3.6 meters. A force of 5 Newtons is applied in the -x direction at the edge of the disk directly to the right of its center. Another force of 28 Newtons is applied directly above the center in the -x direction halfway between the center and edge of the disk. Lastly, a force of 15 Newtons...
A spherical shell centered at the origin has an inner radius of 4 cm and an outer radius of 6 cm. The density, δ, of the material increases linearly with the distance from the center. At the inner surface, δ = 9 g/cm3; at the outer surface, g = 13 g/cm3 (a) Using spherical coordinates, write the density, δ, as a function of radius, p. (Type rho for ρ) (b) Write an integral in spherical coordinates giving the mass of the shell (for...

A disk of mass m, = 70.0 g and radius r , = 4.50 cm slides on a frictionless sheet of ice with velocity v, where v = 12.00 m/s, as shown in a top-down view in figure (a) below. The edge of this disk just grazes the edge of a second disk in a glancing blow. The second disk has a mass m2 = 140 g, a radius r2 = 6.00 cm, and is initially at rest. As the...
