Answer:
Explanation:
In a frictionless system with no acceleration, the tension in the rope must be F along its entire length
FBD analysis of the lower pulley has two upward acting tension vectors F and one downward acting weight vector W
2F = W
F = W/2
FBD analysis of the upper pulley has one upward acting support vector T and three downward acting tension vectors F
T = 3F
T = 3(W/2)
T = 1.5W
Answer:
To summarize, an object moving in uniform circular motion is moving around the perimeter of the circle with a constant speed. While the speed of the object is...
To solve this problem we will apply the concept related to Angular momentum. Said conservation momentum says that its initial state must be equal to that of the final state, that is,
Here,
I = Moment of Inertia
Angular velocity
Rearranging to find the ratio between the moment of inertia we have,
Replacing,
Therefore the correct option is C.
