A hoop of mass 50 kg rolls without slipping.If the center-of-mass of the hoop has a translational speed of 4.0 m/s,the total kinetic energy of the hoop is
E)None of these is correct.
A ball of mass m1,connected to another mass m2 by a string,is whirled at a constant speed in a horizontal circle of radius R equal to 0.800m.If the mass m2 = 5.00 kg,the kinetic energy of the ball is
A thin solid disk of radius R = 0.5 m and mass M = 2.0 kg is rolling without slipping on a horizontal surface with a linear speed v = 5.0 m/s.The disk now rolls without slipping up an inclined plane that is at an angle of 60 degrees to the vertical.Calculate the maximum height that the disk rolls up the incline.
A spherical shell and a solid sphere (both of the same total mass)are rotating about a diameter at the same angular frequency and with the same rotational kinetic energy.What is the ratio of the spherical shell radius to the solid sphere (i.e.,Rspherical shell/Rsolid sphere)?
