On a friction-free ice pond, a hockey puck is pressed against (but not attached to) a fixed ideal spring, compressing the spring by a distance ?x?0. The maximum energy stored in the spring is ?U0 ? , the maximum speed the puck gains after being released is ?v?0, and its maximum kinetic energy is ?K?0. Now the puck is please so it compresses the spring twice as far as before. In this case, (a) what is the maximum potential energy stored in the spring (m terms of ?U?0), and (b) what are the puck’s maximum kinetic energy and speed (in terms of ?K?0 and ? ?0)?
Solution 11 DQ Step 1: In this question , we need to find the maximum potential energy stored in the spring We also need to find maximum kinetic energy and speed of puck Data given Compression of spring x 0 energy stored in the spring U 0 Maximum speed gained by puck v 0 Maximum kinetic energy of the puck K 0
