Acceleration of Forces at Angles

AI Thread Summary
The discussion focuses on a physics problem involving a clerk pulling a box of cans with a force of 176.0 N at a 30-degree angle above the horizontal. The box has a mass of 40.0 kg and a coefficient of kinetic friction of 0.520. Participants clarify that "with the horizontal" refers to the angle of the pull being 30 degrees above the horizontal plane. This understanding is crucial for accurately drawing the free body diagram (FBD) and calculating the box's acceleration. The conversation emphasizes the importance of interpreting angles correctly in physics problems.

A clerk moves a box of cans down an aisle by
pulling on a strap attached to the box. The
clerk pulls with a force of 176.0 N at an angle
of 30.0◦ with the horizontal. The box has a
mass of 40.0 kg, and the coefficient of kinetic
friction between the box and floor is 0.520.
The acceleration of gravity is 9.81 m/s2 .
What is the acceleration of the box?
Answer in units of m/s2.

Okay, this should be a simple problem, but I don't understand what it means when it says 'with the horizontal' and how that would look on my FBD. Help me please?

"with the horizontal" should be "to the horizontal"--that is, she pulls at an angle that's 30 degrees above the horizontal.
 
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'
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...
