The system shown in Figure P5.49 has an acceleration of magnitude 1.50 m/s2. Assume that the coefficient of kinetic friction between block and incline is the same for both inclines. Find (a) the coefficient of kinetic friction and (b) the tension in the string.
A makeshift sign hangs by a wire that is extended over an ideal pulley and is wrapped around a large potted plant on the roof as shown in Figure P6.10. When first set up by the shopkeeper on a sunny and dry day, the sign and the pot are in equilibrium. Is it possible that the sign falls to the ground during a rainstorm while still remaining connected to the pot? What would have to be true for that to be possible? FIGURE P6.10 Problems 10 and 11.
The systems shown below are in equilibrium with m = 6.60 kg and ? = 25.0°. If the spring scales are calibrated in newtons, what do they read? Ignore the masses of the pulleys and strings and assume the pulleys and the incline are frictionless. Four figures each show different orientations of a spring scale connected to various objects. Figure (a): Two objects of mass m are attached to opposite ends of a horizontal spring scale, one on the left end and the other on the right end. The spring scale is positioned at the center of a horizontal tabletop and between two diagonal pulleys which extend outward from the left and right edges of the table. Separate strings are attached to each end of the spring scale and pass over the nearest pulley before suspending an object of mass m beside the table. Figure (b): A diagonal pulley extends outward from the leftmost edge of a horizontal surface. An object of mass m is suspended from a string which passes over the pulley and anchored at the left…
