m.R rough icy This problem will help you learn required concepts such as: . Conservation of Mechanical Energy Rotational Kinetic Energy . Rolling Constraint. so please review them before you begin. A disk of mass m and radius R rolls without slipping down a rough slope of height H onto an iey (frictionless) track at the bottom that leads up a second icy/frictionless hill as shown. a) How fast is the disk moving at the bottom of the first incline? How fast is it rotating (what is its angular velocity)? moves onto the ice (in the middle of the flat stretch in between the hills)? stops rising? b) Does the disk’s augular velocity change as it leaves the rough track and angular velocity change as it leaves the rough track a c) How far, up the second hill (vertically find H’) does the disk go before it
