Question

Two blocks are connected by a string over a frictionless, massless pulley such that one is resting on an inclined plane of 60 degrees and the other is hanging over the top edge of the plane. the hanging block has a mass of 400kg and the one on the plane has a mass of 200 kg. the coefficient of kinetic friction between the block and the inclined plane is 0.45 static is 0.5. the blocks are released from rest. a. what is the value of static friction? b.what is the value of kinetic friction? c. will the blocks move? d> if so what is the aceliration

Explanation / Answer

he answer will depends upon the incline angle of the plane, which you did not provide. Write free body F = ma equations for both blocks. The string tension T will appear in both equations. The other unknown will be the acceleration, a. You should be able to solve for both. The friction force acting on the sliding mass is 400*9.8*cos60*0.5 =F1= calculate your answer as i have no calculator this time A gravity componet of M g sin 60 =F2= CALCULATE YOURSELF also acts on the slid9ing block. Equations of motion are: T - F1 - F2 = Calculate
