Two carts, A and B, are connected by a rope 39 ft long that passes over a pulley P. The point Q is on the floor h = 12 ft directly beneath P and between the carts. Cart A is being pulled away from Q at a speed of 4 ft/s. How fast is cart B moving toward Q at the instant when cart A is 5 ft from Q? (Round your answer to two decimal places.)

Two objects are connected to a rope, and the rope is hung over a pulley connected to the ceiling, as shown in the figure below. Two objects, labeled m1 and m2, are connected to a rope which is hung over a pulley connected to the ceiling. The pulley is of mass M and radius R. An object labeled m1 hangs suspended off the surface on the left side of the pulley. An object m2 is on the right side of...

Mazur 9.40: Two identical 0.50 kg carts, each 0.10 m long, are at rest on a low-friction track and are connected by a spring that is initially at its relaxed length of 0.50 m and is of negligible inertia. You give the cart on the left a push to the right (that is, toward the other cart), exerting a constant 5.0-N force. You stop pushing at the instant when the cart has moved 0.40 m. At this instant, the relative...

Two masses are connected to one another with a massless rope that passes over a massless and frictionless pulley as shown in the figure below. When the two mass system is released from rest, the hanging mass m2 = 31.5 kg accelerates upward at a rate of 2.3 m/s2. The coefficient of kinetic friction between m1 and the incline is 0.08, and the angle of inclination of the ramp is 57 degrees. For the entirety of this problem, air resistance...

Two weights, with masses 25 kg and 10 kg are connected through a lightweight rope over a pulley as shown in figure 2 below. Initially, the 10 kg mass rests on the floor while the 25 kg mass is held in position, two (2) meters above it. a. Using the principle of conservation of energy, determine the speed of the 25 kg mass right before it strikes the floor. b. Determine the acceleration of the 25 kg mass. c. How...

Two blocks are connected by a string that passes over a massless, frictionless pulley, as shown in the figure. Block A, with a mass mA = 2.00 kg, rests on a ramp measuring 3.0 m vertically and 4.0 m horizontally. Block B hangs vertically below the pulley. Note that you can solve this exercise entirely using forces and the constant-acceleration equations, but see if you can apply energy ideas instead. Use g = 10 m/s2. When the system is released...

A hanging weight, with a mass of m1 = 0.355 kg, is attached by a rope to a block with mass m2 = 0.845 kg as shown in the figure below. The rope goes over a pulley with a mass of M = 0.350 kg. The pulley can be modeled as a hollow cylinder with an inner radius of R1 = 0.0200 m, and an outer radius of R2 = 0.0300 m; the mass of the spokes is negligible. As...

At noon, ship A is 150 km west of ship B. Ship A is sailing east at 35 km/h and ship B is sailing north at 30 km/h. How fast is the distance between the ships changing at 4:00 PM? Gravel is being dumped from a conveyor belt at a rate of 30 ft3/min, and its coarseness is such that it forms a pile in the shape of a cone whose base diameter and height are always equal. How fast...
