Question
An assembly of blocks with masses m1=m=10kg accelerates down theramp at an angle theta=60 degrees. Only theleftmost block (m1) experiencesfriction with Kineticcoefficient=0.5, others are frictionless. Find tension in the ropeconnecting two blocks on theramp. an angle theta=60 degrees. Only theleftmost block (m1) experiencesfriction with Kineticcoefficient=0.5, others are frictionless. Find tension in the ropeconnecting two blocks on theramp.Explanation / Answer
the system of two objects will moves down with the accelerationa. The second law of Newton: 2mg*sin60 -*m.g.cos60 =2m*a => a=7.262 m/s2 by applying the 2nd Newton's Law for one object, we get: the tension T mg*sin60 - T=m.a =>T=12.25 N
