1. What is the effect of doubling the object's mass on its angular speed, if everything else stays the same? 2. Since the Earth is rotating at 460 m/s, what keeps us from being flung into space? 3. A hipster frog of mass m = 0.0200 kg is sitting on the outer edge of a vinyl record with radius r = 0.15 m. This record player is extraordinary! The frog's tangential velocity is v = 460 m/s. a. What is the frog's angular speed? b. Centripetal force is what's keeping the frog on the record. With what magnitude force does the frog have to hang on to that record to keep himself from flying off? c. Coincidentally, v = 460 m/s is also the tangential velocity resulting from the rotation of the Earth that a regular, non-hipster toad experiences while just relaxing on a lily pad. He's not gripping onto the surface of the lily pad with as much force as the hipster frog on the record. Why doesn't the toad go flying off into space?
