Problem 1: A 1000.0 kg elevator is controlled with a cable. Friction and air resistance can be ignored. In this problem, the elevator is already moving downward at a constant speed of 1.0 m/s. During this initial stage, the elevator moves with this constant speed for 1.5 seconds. Then, in a 2nd stage, the elevator slows down to a stop with constant acceleration. During this 2nd stage, it takes 0.5 seconds of time to come to a stop. A. Draw...

A mass m1=5.0 kg hangs suspended by a rope from an elevator ceiling. A second mass m2=5.0 kg hangs suspended by a rope from the bottom of mass m1. Starting from rest, the elevator ascends, attaining its maximum speed of 1.8 m/s in 0.80 s. The elevator travels with this constant speed for 5.0 s, undergoes a uniform negative acceleration for 1.5 s, and then comes to rest. Draw a FBD for each mass Find the tension in each rope...

A rudimentary elevator is constructed by connected an elevator car of mass Me = 568 kg to a large counterweight of mass Me = 730 kg. A man of mass m = 90 kg steps on the elevator car and then the counterweight is released. a) Draw the free body diagrams for the elevator car, the counterweight, and the man. b) What is the acceleration of the counterweight (magnitude and direction)? c) What is the tension in the string? d)...

A 40 kg box is sitting on a scale in an elevator because the box and scale need to get to the lab on the second floor of the Science Building. Looking at the scale you realize that it is reading 500 Newtons as the elevator is speeding up. How many forces are acting on the box as it speeds up? Use a stacked addition table to determine the acceleration of the box. Draw a force diagram for the box...

(13.1) An elevator riding in a frictionless vertical shaft has total mass of 1000 kg. (a) The elevator cable exerts a force of 9000 N in the upward direction on the elevator. Determine (i) the acceleration of the elevator, and (ii) how long it takes for the elevator, starting from rest, to attain a speed of 5 m/s. (b) The cable exerts a force of 12000 N [up] on the elevator. Determine (i) the acceleration of the elevator, and (ii)...

A large fish hangs from a spring balance supported from the roof of an elevator. If the elevator has an upward acceleration of 2.45 m/s2 and the balance reads 60.0 N , what is the true weight of the fish? SET UP Draw a sketch of the physical situation, and identify the moving object or objects to which you will apply Newton’s 2nd law. Draw a free-body diagram for each chosen object, showing all the forces acting on that object....
