GOALLESS PROBLEMS: Solve for EVERY kinematic & dynamic UCM variable you can determine. Some problems allow you to draw a System Schema and FBD's other do not because not enough information is provided. You decide when it is possible and when it is not. 18. A 0.5kg rock is being twirled in a vertical circle by a rope and is experiencing an acceleration of 12 m/s2 while traveling in a circle of radius 5.0 m. 19. A 5.0 kg object that has a velocity of 15 m/s and is moving in a circle of radius 1.6m? 20. A 300 kg motorcycle (rider included) has a velocity of 37 m/s as it is moving in a curved path along a flat road of radius 45m? 21. An object is experiencing a centripetal acceleration of 2.0 ml's2 while traveling in a circle at a velocity of 0.35 m/s
