Problem 4 A uniform solid spherical ball of mass M and radius R rests on a horizontal surface. Assume a constant coefficient of friction (this means that the frictional force is equal to the normal force multiplied by u). The acceleration due to gravity is g. At time t 0, the bal is struck impulsively on center, causing it to go instantaneously from rest to initial rotation horizontal speed vo with a no (a) Find the horizontal speed, and the...

Use cylindrical coordinates to work out the volume of a ball of radius 1, and to find the center of mass of the upper half of of the ball. (If you take the hemisphere to have its origin at (0,0,0) and it's base in the XY-plane the z-coordinate of the center of mass is the "average value of z" over the hemisphere, or the total moment divided by the volume.) Parametrize the upper hemisphere using cylindrical coordinates and find it's...
