A string under tension of 50.0 N is used to whirl a rock in a horizontal circle of radius 2.5 m at a speed of 20.4 m/s on a frictionless table. The string passes through a small hole in the table at the center of this circle. As the string is pulled in, the speed of the rock increases. When the string is 1.00 m long and the speed is 51.0 m/s, the string breaks. What is the breaking strength, in Newtons, of the string?

- A variation of the amusement park ride discussed in Problem 11 is the Gravitron, which consists of a rotating cylinder, where riders stand with their backs against the inner surface of the cylinder (see image). As the cylinder rotates faster, riders get stuck to the wall. The effect is great enough, that in some rides, the floor even drops away. Let’s model the Gravitron as a rotating cylinder with vertical walls. The radius of the cylinder is 5.5 m. At one point during the ride, the speed of the Gravitron is 24 rpm, at which point a rider slides down the wall at constant speed. What is the coefficient of kinetic friction between the rider and the wall?arrow_forwardA Stone Age hunter stands on a cliff overlooking a flat plain.

The tension in the vine increases as the rock goes faster and faster. Suddenly, just as the tension reaches 200 N, the vine snaps.
