Question

Block A of mass m₁ slides on a horizontal rough table (kinetic friction μₖ), connected via light string/pulley to hanging block B of mass m₂. Find tension T while A slides toward the pulley.

G1 Physics · Accepted Answer

For A, T−μₖm₁g=m₁a. For B, m₂g−T=m₂a. Solve a=(m₂−μₖm₁)g/(m₁+m₂). Substituting in the first equation gives T=m₁m₂(1+μₖ)g/(m₁+m₂). Answer: C.
