where F k is the frictional force, mg is the weight of the block, T is tension and F n is the normal force acting on the block where m 2 g is the weight of block 2 and T is the tension in the string B) We can use newton's second law, F=ma, to write equations for each block. We know the normal force is equal to: F n = m 1 g We also know the frictional force: F k = μ k F n For block 1: m 1 a = T - F k m 1 a = T - μ

Unformatted text preview: k *m 1 g For block 2: m 2 a = m 2 g - T We can add the equations together to determine the acceleration: (m 1 +m 2 )a = m 2 g - μ k *m 1 g a = [m 2 g - μ k *m 1 g] / (m 1 +m 2 ) We can then substitute our value for a into either the equation for block 1 or 2 to get the tension: T = m 2 g - m 2 a = m 2 g - m 2 *[m 2 g - μ k *m 1 g] / (m 1 +m 2 )...

    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.
