Three blocks are connected as shown in the diagram above. Block A has a mass of 1.1 kg and hangs from a (massless) string that runs over a (massless and frictionless) pulley. The other end of the string is connected to Block B which has a mass of 3.5 kg. The other side of Block B is connected to a (massless) string that runs over a (massless and frictionless) pulley and then connects to the hanging Block C which has a mass of 1.7 kg. Block B is sliding down an (essentially frictionless) plane that is inclined at an angle of θ = 23 degrees from the horizontal, as shown. All of the blocks move together when they are released from rest. Block B slides down and to the right. What is the speed of Block B (in units of meters per second) after it has slid a distance d2 = 0.23 meters, starting from rest?
