A block of mass M sits on top of a horizontal frictionless bench. A string attached to M runs over a massless, frictionless pulley and is attached to a vertically hanging mass 111. Mass M is attached to a horizontal spring of spring constant k whose other end is fixed to a wall. Then system is originally held at rest when the spring is unstretohed and then released. Enter ratios as exact fractions, for example enter % as % not 1667. Do not simplify square roots. for example and sqrt (5) are accepted but not 2.236. (a) Find an expression for the maximum distance that m will fall. I= IE (b) Suppose that m = 30 kg, M = 10 kg, and k = w Calculate the speed of mass am after it has fallen a distance it = 75.6 cm. 1; = mfs
