1. A 1 kg wedge is pulled across a rough floor (uk=0.20) via contact with a 2 kg block as shown below. The shape of the wedge is that of an isosceles right triangle. a rope passes from the 2 kg block and over a mass-less and friction-less pulley and is attached to a hanging mass. Find the minimum value of the hanging mass so that the 2 kg block remains at rest on the inclined surface of the 1 kg block as it accelerates. The coefficients of friction between the 1 kg block and he 2 kg block are us=0.60 and uk=0.40. 2. Newton's Laws of Motion3. We did no problems like this in class before, so I'm pretty stumped on how to solve it, but I got a final answer of 2.3 kg for the hanging mass. Can anyone help? The picture for the problem is shown below.
