3) Jack takes a 4.0-kg bucket of water connected on a cord, and swings it in a vertical circle of radius 85.0 cm at a constant speed of 6.0 m/s. 85cm 85m 100 a) When the bucket passes its highest point, what are the magnitude and direction of its acceleration? 6.am/s) =42.35 m/s ar = (85m) b) When the bucket passes its highèst point, what is the tension in the cord? ニ - mg =Uhg.7.8m/2= 39.2 Ft = Fg +me= 39.2+(10ky.42.35m/s)= 462.7N %3D c) The cord can handle a maximum force of 300N. What is the maximum constant speed that Jack can spin the bucket before the cord breaks?
