Unformatted text preview: Physics 1A Solution 3 November 1, 2019 b) We can write the force balance FNet = m x a in each component for each box: Box A & : T = MAXa Box A y : -mag + FN = MAX0 Box By : T - mBg = mB X (-a) where in the last equation we have used the fact that Box A moves left with the same acceleration as Box Solving we get: B moving downward. We can use the expression for T = mAd in the first equation and plug into the third. MAa - mBg = -mBa a(mAtmB) = mBg a = MBg MATMB From here we can again use T = mAa to find T = - mAmBg MA + MB c) We can plug in to the expression for a that we found: a = a= - mBg 5 kg 10 m/s mAtmB 13 kg + 5 kg = 2.8 m/s2 30 ..

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
