Two blocks (m1=5.5kg, m2=7.2kg ) are connected by a string that passes through a massless pulley as shown in the Figure. The first block with mass m1  slides up the inclined plane when the system is released. The inclined plane makes an angle  θ = 310  with the horizontal and the kinetic friction coefficient between the inclined plane and   m1 is =0.35.   Take  g=10m/s2 Find the speed of the block with mass m2 after it travels h=5.6m.

Two blocks are connected by a string that passes over a massless, frictionless pulley, as shown in the figure. Block A, with a mass mA = 2.00 kg, rests on a ramp measuring 3.0 m vertically and 4.0 m horizontally. Block B hangs vertically below the pulley. Note that you can solve this exercise entirely using forces and the constant-acceleration equations, but see if you can apply energy ideas instead. Use g = 10 m/s2. When the system is released...
