A certain cable of an elevator is designed to exert a force of 4.5 × 10^4 N. If the maximum acceleration that a loaded car can withstand is 3.5 m/s2, what is the combined mass of the car and its contents?

What net force is required to make a 15 kg box move at a constant speed of 2.0 m/s.

If the only forces acting on a 5-kg mass are F1 = (2i- 3j) N and F2 = (6i + 8j) N, what is the magnitude of the acceleration of the particle?

Three forces acting on an object are given by F₁ = (-1.951 +5.653) N, F₂ = (4.751 1.351) N, and F3 = (-401) N. The object experiences an acceleration of magnitude 3.90 m/s². (a) What is the direction of the acceleration? (counterclockwise from the +x-axis) (b) What is the mass of the object? kg (c) If the object is initially at rest, what is its speed after 12.0 s? m/s (d) What are the velocity components of the object after 12.0 s? (Let the velocity be denoted by V.) v m/s

If a mass of 3.46 kg object is attached to a string. If the force of tension in the string is 50.2 N j, what is the magnitude of the object's acceleration?

Two objects are connected by a massless cable passing over a frictionless pulley. Object A is positioned on a table, while object B hangs freely. The coefficient of kinetic friction between object A and the table is 0.09950. If the mass of object A is 150 kg, and the mass of object B is 238 kg, what is the acceleration of the objects?

Two teams of nine members each engage in a tug of war. Each of the first team's members has an average mass of 72 kg and exerts an average force of 1350 N horizontally. Each of the second team's members has an average mass of 77 kg and exerts an average force of 1373 N horizontally.   (a) What is the acceleration (in m/s2 in the direction the heavy team is pulling) of the two teams?

A locomotive is pulling 12 freight cars, each of which is loaded with the same amount of weight. The mass of each freight car (with its load) is 37,000 kg. If the train is accelerating at 0.78 m/s2 on a level track, what is the tension in the coupling between the second and third cars? (The car nearest the locomotive is counted as the first car, and friction is negligible.)

A rock with a density 2.8 times the density of water is dropped into a lake (SG = 0.90). A person dives in and tries to get it out. Which the relationship between the mass of person and the mass of rock so that the person can lift it from the bottom of the lake?

A boat and its passengers have a combined mass of 5.10x10^2 kg. The boat is coasting into a pier at a speed of 1.00 m/s. How great a force is required to bring the boat to rest in 1.00x10^2 s?
