a 1.0 N-weight is hanging at rest as shown. In each case, write in the magnitude of the unknown force.
a) chain with a weight of 2.5 N has a 1.0 N hanging weight
b) chain with a weight of .5 N has a 1.0 N hanging weight
c) stretched elastic band with negligible weight has a 1.0 N hanging weight
an insect inside a bus flies from the back toward the front at 2 m/s the bus is moving in a straight line at 20 m/s what is the speed of the insect relative to earth's surface
THIS IS NO HELP ???
a) F(unknown)= 2.5N + 1.0N
b) F(unknown)= .5N +1.0N
c) F(unknown)= 0N + 1.0N
