A rock is attached to the left end of a meter stick that has the same mass as the rock. The meter stick's length is 1.00 m. How far (in m) from the left end of the meter stick should the triangular pivot be placed so that the stick and rock balance on the pivot

Suppose that 27 j of work is needed to stretch a spring from its natural length of 6 m to a length of 9 m. (a) how much work is needed to stretch the spring from 12 m to 14 m? j (b) how far beyond its natural length will a force of 78 n keep the spring stretched?
