Towing a 25.0 kg suitcase at constant speed with handle at an angle

AI Thread Summary
A woman is towing a 25.0 kg suitcase at a constant speed using a 30.0 N force applied at an angle above the horizontal, while a friction force of 20.0 N acts on the suitcase. The angle of the pull was calculated to be approximately 48.19 degrees using trigonometry. Additionally, a related discussion involved a light string that can support a 24.0 kg load, with a 3.60 kg mass rotating on a frictionless table, leading to a formula for the maximum speed before the string breaks. The conversation emphasizes the importance of personal effort in solving physics problems. Overall, the discussion highlights the application of physics principles in real-world scenarios.

A woman at an airport is towing her 25.0 kg suitcase at constant speed by pulling on a strap at an angle of above the horizontal (Fig. P5.6). She pulls on the strap with a 30.0 N force, and the friction force on the suitcase is 20.0 N


what is the angle she pulls the suitcase with

wait i got it, it's 48.19 lol simple trig problem.
 
A light string can support a stationary hanging load of 24.0 kg before breaking. A 3.60 kg mass attached to the string rotates on a horizontal, frictionless table in a circle of radius 0.800 m. What range of speeds can the mass have before the string breaks?
 
lol i found the answer again...

v = sqrt(235.2*r/m)
 
Guess this means you need to put a bit more of your own effort into these problems before running for help, huh?

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Thread 'A cylinder connected to a hanged 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...
