Rope from ceiling rope from floor physics problem.
In this lesson the physics classroom takes the trouble out of the situation by providing an understandable model for approaching two body situations.
Free body diagrams of forces forces expressed by their components and newton s laws are used to solve these problems.
Answer to a 2 3 kg rope hangs from the ceiling.
That is there s two objects moving together and connected in some manner by a force.
B calculate the magnitude of the force exerted by the floor on student a.
Start with a force diagram of the ball including a coordinate system.
A rope of negligible mass passes over a pulley of negligible mass attached to the ceiling as shown above.
It s referred to as a two body problem.
And when that happens it s double trouble for physics students.
The rope has negligible mass.
The total length of the rope is 2 4m.
