two blocks are connected by a string . they are released from rest. if the coefficient of friction between m1 and the surface is μ, find the common speed of the blocks at the instant when they have moved a distance L.

Question

two blocks are connected by a string . they are released from rest. if the coefficient of friction between m1 and the surface is μ, find the common speed of the blocks at the instant when they have moved a distance L.

Adhitya · Answer

W1=um1gl W2=m2gl Therefore, Net work =W2-W1(friction does negative work) =(m2-m1u)gl Now according to W-E Theorem, 1/2(m1+m2)v^2=(m2-um1)gl Therefore v=&radic;2(m2-um1)gl/&radic;(m1+m2).
