SEE ATTACHMENT #1 for a diagram showing parameters.
Frictionless block M1 = 3.6 kg, is connected by a cord to block M2 = 7.5 kg. They are placed on a plane which is at angle b= 25 degrees. The coefficient of friction f = .45 between M2 and the plane. Find the tension in the cord as they slide down.© BrainMass Inc. brainmass.com March 4, 2021, 5:43 pm ad1c9bdddf
