Two blocks are connected by a massless string, which passes over a frictionless pulley, as shown. The inclines are rough and have coefficient of kinetic friction ^ = 0.100 for both blocks. The blocks have masses mi = 3.50 kg and m 2 = 8.00 kg. The 8.00 kg block slides to the right a distance of 0.500 m. (a) [3 pts.J What is the magnitude of the frictional force on

    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.
