A box of mass mi = 1kg is connected to a string on one end and a spring with spring constant k = 100M on the other end. The spring begins at its natural length. The pulley is massless, frictionless, and does not rotate. When the m2 = 5kg block is connected to the string at a height h 3m above the spring's natural length, the system will move. You may assume the 5m box never hits the ground. 5m a) Write the potential energy of the system U(y) as a function of the elongation y of the spring away from the natural length m b) What is the maximum elongation of the spring? k du (y) = 0. This will be c) Find the value of y such that dy the minimum potential energy d) Find the maximum speed mi will reach.
