V PartB In what direction were Emma and Clara originally traveling? Give your answer as an angle in degrees measured CCW from due East (when looking Down); the size of the angle should be less than 180 degrees. If the angle would be larger than 180 degrees. instead measure CW from due East and give your answer as a negative angle. degrees CCW from East R_equest Answer V Part6 How much kinetic energy was added to the Emma-Clara system by Clara's push? .690-7 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 lollowing problem are skating with the control mechanism turned off! In other words, they have the capability of completely lrictionless 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. Marty and Jennifer's twin granddaughters, Emma and Clara, 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 is 22.50 kg (the mass of each skater includes the mass of her hoverboard). Suddenly, Clara spots an obstacle ahead; to save them both from collision with the obstacle, she gives Emma a two-handed horizontal push. As a result, Emma ends up traveling at 1'90 m/s , due North, and Clara ends up traveling at 2.30 m/s , 37.0 degrees North of East.
