AI Thread Summary
The discussion centers on a request for assistance with a physics take-home test, specifically regarding a problem involving a skier's speed on a slope with friction. Participants emphasize the importance of showing work and understanding the concepts rather than simply providing answers. However, one contributor warns against seeking help for test questions, citing potential violations of academic integrity and the risk of expulsion. The conversation highlights the balance between seeking guidance and adhering to honor codes in educational settings. Ultimately, the emphasis is on learning and ethical conduct in academic work.

Ok, I am horrible at physics and I have a take home test and I need some help on some of the questions. So if you know how to do them pllease let me know and help me

1.)A 62 kg person is going down hill on a ski run angled at 37 degrees from the horizontal. The coefficient of kinetic friction between the skis and the snow is .15. How fast is the skier going at 5 seconds after starting from rest?

We won't solve problems for you. Please show us your work, let us know where you're stuck, and we'll give you guidance so that you can solve the problem yourself.

Edit: Actually, because you're working on a test, I'm afraid we cannot help you at all. Asking for help from other people for a test is certainly a violation of your school's honor code, and is probably justification for expulsion.

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}...
