A dancer is standing on one leg on a drawbridge that is about to open. The coefficients of static and kinetic friction between the drawbridge and the dancer's foot are μs and μk, respectively. n represents the normal force exerted on the dancer by the bridge, and Fg represents the gravitational force exerted on the dancer, as shown in the drawing. (Intro1 figure) For all the questions, we can assume that the bridge is a perfectly flat surface and lacks the curvature characteristic...

A couple of problems I was struggling with on my previous assignment 3. A fire dancer in china town makes circles with a ball on a string that is 25cm long. The amount of rotations the fireball makes count it to be 4 times every second. a. Find the speed and acceleration of the fireball. The dancer lets go of the string and the ball shoots into the air straight at you with an angle of 35 degrees to the...
