1. The problem statement, all variables and given/known data A 5.00kg hanging block is connected by a string over a light pulley to a 3.00kg block that is sliding on a flat table. The coefficient of friction between the 3.00kg block and the surface is 0.400. The system starts from rest. What is the speed of the 5.00kg block when it has fallen 1.50m? x1 = 0 x2 = 1.50m Block 1 m1 = 5.00kg Block 2 m2 = 3.00kg coefficient of friction = 0.400 2. Relevant equations Block 1 x: Fnet = T1 + Tf = ma y: Fnet = Fg + N = ma = 0 Block 2 x: Fnet = ma = 0 y: Fnet = T2 + Fg = ma = T2 - mg = ma 3. The attempt at a solution a = (t1 + tf) / m a = (t2 + Fg) / m (t1 + tf) /m = (t2 + Fg) / m Plug block 2 (x-axis) t2 = ma + mg into block 2 equation ma + mg + T1 = ma mg + T1 = ma - ma = 0 T1 = -mg I don't know if this is right. Does that mean the tension on the sliding surface is equivalent to the negative Fg?
