Problem 5 A man is swinging an object, attached to a string, in a circle over his head (see the sketches). Side view Top view (a) Draw a free-body diagram for the object. Notice the string is not drawn horizontal in the "side view" diagram above. Why is that? (b) If the mass of the object is 1 kg, what is the vertical component of the tension? (c) If the object makes 3 turns per second, and the radius of...
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...
