An elevator cabin has a mass of 364.1 kg, and the combined mass of the people inside the cabin is 180.9 kg. The cabin is pulled upward by a cable, with a constant acceleration of 1.75 m/s2. What is the tension in the cable?

A horizontal force of 87.2 N is applied to a 40.5 kg crate on a rough, level surface. If the crate accelerates at 1.23 m/s2, what is the magnitude of the force of kinetic friction (in N) acting on the crate?

A lamp hangs from the ceiling of an elevator as it slows to a stop as it approaches the top floor in a building. The tension in the cord holding the lamp is 90 N and the elevator slows at a rate of 3.2 m/s^2. What is the mass of the lamp?

An elevator cab that weighs 27.3 kN moves upward. What is the tension in the cable if the cab's speed is (a) increasing at a rate of 1.10 m/s² and (b) decreasing at a rate of 1.10 m/s²? (a) Number Units (b) Number i Units

A stack of two crates is being accelerated upwards by two cables. The cables are directly attached to crate 1 and the tension in each cable is 3248 N. You may assume that the masses of the cables are negligible compared to the masses of the crates. The acceleration of the crates is? bottom crate crate 1 is 109 kg. the top crate is 248 kg.

An elevator cab that weighs 28.6 kN moves upward. What is the tension in the cable if the cab's speed is (a) increasing at a rate of 1.36 m/s? and (b) decreasing at a rate of 1.36 m/s?? (a) Number i Units (b) Number i Units

A box of mass 15.7 kg slides down an inclined plane without friction. If the acceleration, a, of the box along the direction of the plane is 4.1 m/s2, what is the angle θ (in degrees) of the plane with respect to the horizontal?

An Atwood machine consists of two masses hanging from the ends of a rope that passes over a pulley. Assume that the rope and pulley are massless and that there is no friction in the pulley. If the masses have the values ?1=19.5 kg and ?2=12.5 kg, find the magnitude of their acceleration ? and the tension ? in the rope. Use ?=9.81 m/s2.
