[answerhappygod]

Two objects (m1 = 5.45 kg and m2 = 3.20 kg) are connected by a
light string passing over a light, frictionless pulley as in the
figure below. The 5.45-kg object is released from rest at a point h
= 4.00 m above the table. Two objects are connected by a taught
string passing over a pulley. An object labeled m2 rests on a
table, and an object labeled m1 dangles a distance h above the
table. (a) Determine the speed of each object when the two pass
each other. m/s (b) Determine the speed of each object at the
moment the 5.45-kg object hits the table. m/s (c) How much higher
does the 3.20-kg object travel after the 5.45-kg object hits the
table? m
