An 81 kg man lowers himself to the ground from a height of 10.6 m by holding onto a rope that runs over a frictionless pulley to a 60 kg sandbag.
(a) With what speed does the man hit the ground if he started from rest?
(b) What can he do to make him hit the ground slower?
The Attempt at a Solution
attempt for part a: no idea... i drew diagram, labeled forces, but cant seem to go beyond that.
attempt for part b: hold the string attached to the sandbag and pull down as he is going downward.
