AI Thread Summary
A 5.0 kg mass is accelerated up a 4.0 m ramp inclined at 30º by a falling 20.0 kg mass over a frictionless pulley, with a coefficient of kinetic friction of 0.26. To solve for the acceleration of the 5.0 kg mass, a free body diagram (FBD) is essential to analyze the forces acting on both masses. The equation ma = mg - Ft is crucial for determining the forces involved. The discussion emphasizes the importance of using FBDs to accurately calculate the acceleration and tension in the rope. Understanding these principles is vital for solving the problem effectively.

Homework Statement



A 5.0kg mass is accelerated from rest at the bottom of the 4.0 m long ramp by a falling 20.0kg mass suspended over a fictionless pulley. The ramp is inclined 30º ramp from the horizontal, and the coefficient of kinetic friction = .26.
a. Determine the acceleration of the 5.0 kg mass along the ramp.
b. Determine the tension in the rope during the acceleration on the 5.0 kg mass along the ramp.

Homework Equations



ma = mg - Ft for the lower block

The Attempt at a Solution



what do I do with the block on the inclined plane?
 
Physics news on Phys.org
Hint: free body diagram.
 
FBD is a necessity...
 
You will have two of them - one for the block on the slope and one for the falling mass.
 
As stated in the previous comments, a FBD is useful. With that you will be able to analyze all the forces acting on the masses and from there find the solution.

Remember F = ma!
--Without a doubt, the most important equation for mechanics--
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
