Acceleration

AI Thread Summary

The discussion centers on calculating the acceleration of a ship launched down an 8-degree ramp with a coefficient of kinetic friction of 0.06. Participants are exploring the relevant formulas, including the forces acting on the ship, such as gravitational force and friction. The equations discussed include f=mg sin(θ) for the force due to gravity and N=mg cos(θ) for the normal force. The net force equation, Fx=max=Fgx + f, is also mentioned to find acceleration. Understanding these relationships is crucial for determining the ship's acceleration down the ramp.

I'm not sure which formula to use.
There's f=mg sin0=MsN
N=mg cos0
Fx=max=Fgx +f
max= mg sin0 - Mmg cos0
Mk=Fkx/N

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 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:

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...
