The Attempt at a Solution



IMG_6413.jpg
The above is my attempt to solve question a), is this right approach? Now all i need to do is solve for theta? Or am i completely off track?

Also, i have no idea how to approach question b). some insight would be helpful... Thanks!

Yes, you have the correct approach. Yes, now solve for θ.

Solving (a) will help you see how to answer (b).
 
thanks, i figured both of them out :)
 
Looks like you're on the right track. Google trigonometric identities to figure out how to solve the quadratic. You'll get two angles as a solution.
 
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...
