Question 21 of 25 f 5.5 E 5 View Policies Current Attempt in Progress The gure shows that if we hang a block on the end of a spring with spring constant k, the spring is stretched by distance h : 2.5 cm. If we pull down on the block a short distance and then release it, it oscillates vertically with a certain frequency. What length must a simple pendulum have to swing with that frequency? E 'r i"?
