A glider (mass = 0.12kg ) on a frictionless horizontal air track is connected by a light string over a pulley to a metal block (mass = 0.13kg ) hanging vertically (see figure below). The objects are released from rest and move 0.44 m .
a)Find the objects' acceleration.
b)Find the net work done on each.
c)Find the work done by the string on each.
d)Find the work done by gravity on the hanging mass.
