Question

Two blocks are connected by a light string that passes over a frictionless pulley as in the figure below. The system is released from rest while m₂is on the floor and m₁is a distance h above the floor.

(a) Assuming m₁ > m₂, find an expression for the speed of m₁just as it reaches the floor. (Use any variable or symbol stated above along with the following as necessary: g.)

v_f =

(b) Taking m₁ = 7.0 kg, m₂ = 3.9 kg, and h = 3.9 m, evaluate your answer to part (a).

(c) Find the speed of each block when m₁has fallen a distance of 1.2 m.
