Hi guys,
This is my first post on this forum and I was hoping you could help me.

I'm in the middle of my coursework and I need help working out velocity, here's the info:

Height (cm) Distance (cm)
2.4 20
3.7 30

Average Time (Sec) Speed (cm/s) Velocity (cm/s)

0.55 36.50 2.17
0.80 37.50 2.69

I have this really bad feeling that the velocity is wrong. Can anyone help me out?
Pleaseee! I'm really counting on you lot!

Hi,Physssics, welcome to PF. It would be beneficial if you could state the problem or experiment more clearly, so we can better see what you are looking for. Please show what formulas you are using and why, and how you are arriving at your answers, after first defining the problem. Use the format provided when you post.

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...
