Consider Mass

1=80kg

on the level roof of a building and hanging Mass

2=65kg

conne mass-less pulley as shown below. The coefficient of kinetic friction between. Mass 1 and

t

is 0.4 . Mass 1 is held in place by a construction worker, such that Mass 2 is

2m

above the the construction worked sneezes and lets go of Mass 1. How fast is Mass 2 graveling just ground? Assume Mass 1 stays on the roof.
