Two masses are connected by a light string passing over a frictionless pulley as shown on Figure. The M2= 6.1 kg mass is released from rest at height h = 2.8 m . We are given that M1=2.7 kg and I, the moment of inertia of the pulley is I = 0.198 kg m2 and its radius is R = 0....

I've asked a similar qustion earlier and now I think I have drawn the correct free body diagram and go about solving the problem. The only thing is I do not know how to solve it. a block (mass m1) on a smooth horizontal surface, connected by a thin cord that passes over a ...

A block of mass m1 = 13.5 kg rests on a wedge of angle θ = 27∘ placed over a table.. An inextensible string is attached to Block M1, passes over a frictionless pulley at the top of the wedge, and is then attached to another block of mass M2 = 3 kg. The coefficient ...

Three boxes are connected by cords, one of which (mA) wraps over a pulley having negligible friction on its axle and negligible mass and two boxes (mB & mC) are hanging. The masses are mA = 22.0 kg, mB = 40.0 kg, mC = 16.0 kg. -When the assembly is released from rest, what is ...

A block of mass m1 = 28 kg rests on a wedge of angle θ = 47∘ which is itself attached to a table (the wedge does not move in this problem). An inextensible string is attached to m1, passes over a frictionless pulley at the top of the wedge, and is then attached to ...
