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 bowling ball weighing 71.2 NN is attached to the ceiling by a 3.50 mm rope....
A bowling ball weighing 71.2 NN is attached to the ceiling by a
3.50 mm rope. The ball is pulled to one side and released; it then
swings back and forth like a pendulum. As the rope swings through
its lowest point, the speed of the bowling ball is measured at 4.40
m/s.
Part A
At that instant, find the magnitude of the acceleration of the
bowling ball.
Part B At that instant, find the direction of the acceleration of...

A 3.8-m-long rope of mass 1.2 kg hangs from a ceiling. part A:What is the wave speed in the rope at the bottom end? Part B:What is the tension in the rope at the top end, where it is attached to the ceiling? Part C:What is the wave speed in the rope at the top end? Part D:It can be shown that the average wave speed in the rope is 1/2 sqrt(gL), where L is the length of the rope....

A 91.0-kg mail bag hangs by a vertical rope 3.9 m long. A postal
worker then displaces the bag to a position 2.9 m sideways from its
original position, always keeping the rope taut.
Part A
What horizontal force is necessary to hold the bag in the new
position?
Express your answer with the appropriate units.
Part B
As the bag is moved to this position, how much work is done by
the rope?
Express your answer with the appropriate...

A 57.0 kg box hangs from a rope. What is the tension in the rope if: A) The box is at rest? B)The box moves up a steady 5.20 m/s ? C)The box has vy = 4.90 m/s and is speeding up at 4.70 m/s2 ? The y axis points upward. Express your answer with the appropriate units. D)The box has vy = 4.90 m/s and is slowing down at 4.70 m/s2 ?
Two blocks are connected by a massless rope.
Two blocks are connected by a massless rope. The rope passes over an ideal (frictionless and massless) pulley such that one block with mass m1=13.75 kg is on a horizontal table and the other block with mass m2=6.5 kg hangs vertically. Both blocks experience gravity and the tension force, T. Use the coordinate system specified in the diagram. Part (a) Assuming friction forces are negligible, write an expression, using only the variables provided, for the acceleration that the block of mass...
