AP Physics Problem: Need Help Solving! | View the Question Now

AI Thread Summary
The discussion revolves around a request for help with an AP Physics problem, but the original poster is directed to provide a complete statement of the problem instead of simply asking for a solution. Forum members emphasize the importance of sharing initial attempts to solve the problem for better guidance. The links provided by the poster are deemed unhelpful, as they require registration to access the content. Overall, the community encourages collaboration and problem-solving rather than providing direct answers. Clear communication and sharing of information are essential for effective assistance in academic discussions.

Short answer, No. We will not solve the problem FOR you. If you wish to show us what you have tried, we can attempt to guide you to a solution.

Next problem, you link does not show me the problem. Please post a complete statement of the problem along with your initial efforts.

I'm afraid you are going to have to write out the problems in your posts (you have a second one on this forum with a defective link). The site you are referring us to requires that the user register for an account, which is not something reasonable to ask people on a forum to do if you are asking for their help...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Struggle to understand the concept of the question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
