!!!Nonuniform Circular Motion a 500 g ball rotates on a table while attached to a 1.2 m long tube. A force of 4 N is applied perpendicularly to the end of the tube. the max tension the tube can withstand is 50 N. if the ball starts from rest, how many revolutions does it make before breaking. friction is negligible. m=500 r=1.2 F_perpendicular=4 F_radial_max=50 v_o=0 revolutions=?
