Question

Two blocks are connected by a light string that passes
over a frictionless pulley as in Figure P5.38. The system is released from rest while m ₂ is on the
floor and m₁ is a distance h above the
floor. (a) Assuming m ₁ >m ₂, find an
expression for the speed of m₁ just
as it reaches the floor. (b) Taking
m ₁ = 6.5 kg, m ₂ = 4.2 kg, and
h = 3.2 m, evaluate your answer to
part (a), and (c) find the speed of
each block when m₁ has fallen a distance
of 1.6 m.
