Projectile motion on an inclined plane

AI Thread Summary
The discussion focuses on determining the optimal angle θi for maximum distance d of a projectile fired up an incline with angle ϕ. Participants express confusion over solving the problem and receiving syntax errors when inputting answers into a program. It is suggested that the syntax error may stem from incorrect formatting of the answer rather than a misunderstanding of the physics involved. The importance of adhering to the program's input requirements is emphasized. Clarification on the correct equations and input format is necessary for successful completion of the task.

Homework Statement


A projectile is fired up an incline (incline angle ϕ) with an initial speed vi at an angle θi with respect to the horizontal.



Homework Equations


For what value of θi is d a maximum, and what is that maximum value? (Use v_i for vi, phi for ϕ, and g as appropriate. ϕ is in radians.)

θ>">i =
dmax =


The Attempt at a Solution


Ok so I get so confused with these problems...I did it but the program i have to put it into keep saying syntax error, I don't know if i am wrong or if the program just isn't reading it right...

If it is responding with syntax error, I would think that you are just not inputting your answer in the form that the program needs it to be in.
 
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'

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...
