Three sleds are being pulled horizontally on frictionless horizontal ice using horizontal ropes
(Fig. E5.14). The pull is of magnitude 190 N. Find (a) the acceleration of the system

Two 25.0-N weights are suspended at opposite ends of a rope that passes over a light, frictionless pulley. The pulley is attached to a chain from the ceiling. (b) What is the tension in the chain?

A 550-N physics student stands on a bathroom scale in an elevator that is supported by a cable. The combined mass of student plus elevator is 850 kg. As the elevator starts moving, the scale reads 450 N. (a) Find the acceleration of the elevator (magnitude and direction).

A light rope is attached to a block with mass 4.00 kg that rests on a frictionless, horizontal surface. The horizontal rope passes over a frictionless, massless pulley, and a block with mass m is suspended from the other end. When the blocks are released, the tension in the rope is 15.0 N. (b) What is the acceleration of either block?

A light rope is attached to a block with mass 4.00 kg that rests on a frictionless, horizontal surface. The horizontal rope passes over a frictionless, massless pulley, and a block with mass m is suspended from the other end. When the blocks are released, the tension in the rope is 15.0 N. (c) Find m.

A 75.0-kg wrecking ball hangs from a uniform, heavy-duty chain of mass 26.0 kg. (b) What is the tension at a point three-fourths of the way up from the bottom of the chain?

A 50 kg box hangs from a rope. What is the tension in the rope if: (c) The box has vy = 5.0 m/s and is speeding up at 5.0 m/s^2

A 50 kg box hangs from a rope. What is the tension in the rope if: (b) The box moves up at a steady 5.0 m/s?
