(mu)k is a force? Isn't μk, the coefficient of kinetic friction?Vitani11 said:2 masses m1 and m2 are attached by a string to a massless pulley. mass 1 is on the surface while mass 2 is hanging off. mass 1 experiences a friction force (mu)k.
Do you mean what is the velocity of mass 1 in terms of the velocity of mass 2?What is the acceleration of the system? What is the velocity of mass 1 in terms of mass 2?
Well, if the string remains taught then they'll certainly have the same speed. Technically their velocities would be different since they are moving in different directions (velocity is a vector while speed is a scalar).Vitani11 said:Don't these masses move at the same velocity?
Okay, that's clear now. So you now know that both masses will move with the same speed. Was that your question?Vitani11 said:I mean a system where one mass is on a horizontal surface with friction and the other is hanging off the edge connected by a string over a pulley. For some reason I was thinking atwoods machine. But yes that is what I mean
An Atwood machine is a simple mechanical device used for demonstrating principles of physics, such as force, gravity, and acceleration. It consists of two masses connected by a string, with one mass hanging over a pulley.
The velocity of masses on an Atwood machine can be calculated using the formula v = √(2gh), where v is the velocity, g is the acceleration due to gravity, and h is the height difference between the two masses.
The velocity of masses on an Atwood machine is affected by the difference in mass between the two masses, the length of the string, and the acceleration due to gravity. Friction and air resistance can also affect the velocity.
When the masses on an Atwood machine are unequal, the velocity will be affected by the difference in mass between the two masses. The heavier mass will have a slower velocity, while the lighter mass will have a faster velocity.
Studying the velocity of masses on an Atwood machine can help us understand principles of physics, such as force, acceleration, and gravity. It also allows us to make predictions and calculations about the motion of objects in real-world scenarios.
