a ball of mass m1 and ablock of mass m2 are attached by a light weight cord that passes over a frictional pully negligeable mass. the block lies on an inclined plane of an angle teta. draw the free body diagram. find the magnitude acceleration of the two object and the tension in the cord.

Question

a ball of mass m1 and ablock of mass m2 are attached by a light weight cord that passes over a frictional pully negligeable mass. the block lies on an inclined plane of an angle teta. draw the free body diagram. find the magnitude acceleration of the two object and the tension in the cord.
a) if the inclined plane is frictionless
b) if the inclined plane has coeffient of kf meuk

bobpursley · Answer

I assume m1 is on the incline. summing forces on the rope then toward m2 m2*g-m1*sinTheta*g=(m1+m2)a if no friction m2*g-m1*sinTheta-m1*mu*cosTheta= (m1+m2)a with friction.
