Block A sits on a horizontal tabletop. There is friction between the surface and Block A. The string passes over a frictionless, massless pulley. Block B hangs down vertically. When the two blocks are released, Block B accelerates downward at a rate of 2.030 m/s2. Block A (Mass = 3.678 kg) and Block B (Mass = 3.040 kg) are attached by a massless string.
a. What is the tension in the string?
b. What is the magnitude of the force of friction acting on Block A?
c. What is the coefficient of friction between the tabletop and Block A?
I'm very lost. Please help! Thanks
