Object rotating on a string of changing length. A small mass m attached to the end of a string revolves in a circle on a friction-less tabletop. The other end of the string passes through a hole in the table. Initially the mass revolves with a speed 2.4 m/s in a circle of radius 0.80 m. The string is then pulled slowly through the hole so that the radius i reduced to 0.48 m. The final speed is 4.0 m/s...
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...
A rope of total mass m and length L is suspended vertically with an object of mass M suspended from the lower end. Find an expression for the wave speed at any point a distance x from the lower end, and calculate the time needed for the transverse pulse to travel the length of the rope. The rope has a length of 39.2 m and a mass of 1.00 kg. Suspended object has a mass of 8.00 kg.
