Hello, I incorrectly answered this question in my PHY151 term test and am currently preparing for my deferred final exam. The professor's answer is below. It involved a tricky amount of algebraic manipulation to get here and it would be helpful, in the future, to understand what variables I want in my equation and what I want to get rid of. Is it safe to assume that I don't want to have V1' in my equation for V2' and vice versa? Is that why I couldn't simply re-arrange my conservation of momentum equation? Also, does it matter if the particles are going in the same direction or opposite directions? Thanks!

InstructorI’d have to see your work in getting these. But you would start with:

could you tell me which topic corresponds to which topic of the textbook though, I think it is in 1.1-5, 12.1-12.10, 13.1-13.3, if that is the case where it ends to in Wizeprep

Instructoragain, you should check the course syllabus and with your instructor to confirm and get the latest and most correct information for what's on the assessment and what is covered.

Instructorcan you provide a syllabus or course outline for PHYS 142 that indicates that? i'll need that to request an update to that Wizeprep resource. thx.

how would i solve this (7.95924 x 10^-5 km/s + 3.4456 x 10^-4 km/s) (1.31 x 10^7)

Instructorhi. not seeing what the units of the "1.31x10^7" is, or if you need to keep with Sig Figs, but here's how it would go...

Instructor1cm = 0.3937 inches therefore 23.3 inches will be 23.3/0.3937 cm which is 59.1cm (this is 3 significant figures).

Hello, how does one go about answering a question like this? I am just studying for the final and can't seem to get the correct answer no matter the option I try.

Thank you

InstructorHello, we usually only answer questions regarding the problems we have in Wize courses but I can give you some hint how to approach this problem :)
The maximum of the status friction is equal to mu_s*N which is in this case mu_s*mgCos(theta). As long as the downward force acting on the mass I less than this number, it does not move and it remains in the static equilibrium. There is already a downward force of gravity with the size of mg*Sin(theta) along the surface acting on the mass. So, the difference between the maximum static friction and this force is the largest possible T on the mass to keep it still in the static equilibrium. I hope it helps.

Do you believe the conceptual or the mathematical aspect of physics is more difficult for students to comprehend?
M
Mohammad M
InstructorThe conceptual part is definitely the hardest part. Learning the mathematical part is easy, but if you don't understand the concept behind the equations they are useless!

Why is physics important?
M
Mohammad M
InstructorYou can see and use physics in your daily life. It has happened a lot to me to solve a problem that I have encountered in my life with laws of Physics :) Also, physics is looking for some of the most fundamental questions that human being has been always curious about such as the origin of the world. Finally, If you understand laws of nature, you can harness them to create new technology and make our life more pleasant. All engineers have root in physics :)
