1. (7 points, suggested time 13 minutes)
Two blocks, with masses m and 3m, are attached to the ends of a string with negligible mass that passes over a
pulley, as shown above. The pulley has negligible mass and friction and is attached to the ceiling by a bracket.
The blocks are simultaneously released from rest.
(a) Derive an equation for the speed v of the block of mass 3m after it falls a distance d in terms of m, d, and
physical constants, as appropriate.
