A small object of mass m moves in a horizontal circle of radius r on a rough table. It is attached to a horizontal string fixed at the center of the circle. The speed of the object is initially v0. After completing one full trip around the circle, the speed of the object is 0.5v0. (a) Find the energy dissipated by friction during that one revolution in terms of m, v0, and r. (Use any variable or symbol stated above...

Calculate the net acceleration of an object moving in a circle of radius 20 m if the object is moving at a constant speed of 15 m/s. Also calculate the net acceleration of the object when it speeds up from 15 m/s to 60 m/s in 5 seconds at the instant when its moving at 15 m/s and when it is moving at 60 m/s.
The centripetal force on an object of mass m moving in a circle of radius r with a speed v is: ? = (??^2)/? . Determine the centripetal force and uncertainty for m = 0.80 ± 0.02 kg, r = 1.22 ± 0.02 m, and v = 10.1 ± 0.2 m/s.
A disk of radius 2.05 m rotates about its axis. Points on the disk\'s rim undergo tangential acceleration of magnitude 2.71 m/s2. At a particular time the rim has a tangential speed of 1.51 m/s. At a time 0.923 seconds later, what is the tangential speed, v, of a point on the rim, the magnitude of the point\'s radial acceleration, ar, and the magnitude of its total acceleration, atot?
