A chain, total length h meters long, is sitting on a table. C meters hang down from the table. The chain is let go from rest at time t=0 . The table is frictionless. Find the equation of motion, x(t) Hint: Second order differential equations that can be reduced to cosh if x is defined posative downward. I need a jump start I guess. No masses are given or anything.... I can write a DE if there is air resistance. a + kv = g ?
