  1. Warmup An object revolves once every 0.5 seconds, at a radius of 5m from its center of rotation. It has a mass of 2 kg. What is its: angular velocity tangential velocity rotational inertia rotational momentum the centripetal force required to turn it inward

  2. Universal Law of Gravitation F = -G * m1 * m2 r2 G = 6.674×10−11 N m2 kg−2 r = 6378100 m mearth= 5.9742 × 1024kg
