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...

A uniform rod of mass 3.00x10-2kg and length 0.420m rotates in a horizontal plane about a fixed axis through its center and perpendicular to the rod. Two small rings, each with mass 0.170kg , are mounted so that they can slide along the rod. They are initially held by catches at positions a distance 5.50x10-2m on each side from the center of the rod, and the system is rotating at an angular velocity 27.0rev/min . Without otherwise changing the system,...

tion 9 of 15 > A horizontal circular platform rotates counterclockwise about its axis at the rate of 0.955 rad/s. You, with a mass of 69.9 kg, walk clockwise around the platform along its edge at the speed of 1.21 m/s with respect to the platform. Your 21.1 kg poodle also walks clockwise around the platform, but along a circle at half the platform's radius and at half your linear speed with respect to the platform. Your 17.7 kg mutt,...

A non-uniform density cylinder has a radius R=6m. The rotational inertia of this cylinder can be taken to be I=βMR2, where β is unknown and M is the mass of the cylinder. The cylinder is initially rotating with angular velocity ω0= 1.00rad/s, and is placed on a rough horizontal surface. The speed of the center of mass (CM) of the cylinder, as it is placed on the surface, is 0. The cylinder at first rolls and slips. Just as it...

15 > A horizontal circular platform rotates counterclockwise about its axis at the rate of 0.813 rad/s. You, with a mass of 68.9 kg, walk clockwise around the platform along its edge at the speed of 1.17 m/s with respect to the platform. Your 20.1 kg poodle also walks clockwise around the platform, but along a circle at half the platform's radius and at half your linear speed with respect to the platform. Your 18.9 kg mutt, on the other...

uniform rod of mass 3.30×10−2 kg and length 0.450 m rotates in a horizontal plane about a fixed axis through its center and perpendicular to the rod. Two small rings, each with mass 0.250 kg , are mounted so that they can slide along the rod. They are initially held by catches at positions a distance 5.40×10−2 m on each side from the center of the rod, and the system is rotating at an angular velocity 30.0 rev/min . Without...

A circular annulus, of mass M, inside radius a and outside radius 2a, is given an angular speed w about an axis, through its center perpendicular to its plane, which is horizontal. It is then gently placed on a rough horizontal plane, the coefficient of friction being u. Show that the annulus will start rolling without slipping after a time (10aw/13ug). The experiment is repeated in a space craft on a circular orbit around the earth. State giving reasons, whether...
