    Collision Rotation
AI Thread Summary
To determine the velocity v required for a cube to topple off a table when it collides with a block, one must consider the cube's mass M, dimensions, and moment of inertia, which is given as 8Ma²/3. The problem involves analyzing the rotational dynamics around one edge of the cube as it approaches the table's edge. A sketch is recommended for visualizing the forces and moments acting on the cube during the collision. Understanding the concept of toppling is crucial for solving this problem effectively. The discussion emphasizes the importance of applying physics principles to homework problems involving collision and rotation.

A cube with mass M and length 2a, move in the velocity v on the friction-less horizontal table, when it closes to the end of the table, it is stopped by the long block(the height can be ignored), ask what is the value of v to topple from the table? ( note: use one side of cube as the rotating axis and moment of inertia is 8Ma2/3)

A sketch would help to understand what is going on.

What did you figure out so far? This is a necessary part of homework problem threads.

I figured it out. I remember the concept of topple the object.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
