Perhaps in the distant future skateboards might be replaced by hoverboards, though it is not clear what mechanism the hoverboard "skaters" might use to control their hovering boards. Whatever mechanism that might be, the skaters in the following problem are skating with the control mechanism turned off! In other words, they have the capability of completely frictionless motion in a horizontal plane, but absolutely no control of their speed or direction (except by colliding with objects at the hoverpark or with each other). We will assume that (at least at the hoverpark) the force that makes the boards hover is a purely magnetic repulsion between the boards and the hoverpark surface. You can see a video of a primitive version of a hoverpark here. Esteban and Jessica's twin granddaughters, Emma and Clarita, are preternaturally talented at riding hoverboards. One fine day, the young twins, each riding her own hoverboard, are cruising across the hoverpark arm-in-arm. The mass of each twin…

Question 4 m k X = 0 An assembly of blocks sits on a very smooth floor (see Figure). The bottom block (mass M) is connected to a spring. The top block (mass m) rests on the bottom block. There is a static friction interaction between the blocks; however, the bottom block slides smoothly along the floor. If the spring constant k is 94.7 N/m, M = 1kg, m = 0.5 kg and µ, is 0.20 what is the maximum oscillation amplitude possible without the top block slipping? (PUHQ0445)
