The 4.00kg block in the figure is attached to a vertical rod by means of two strings. when the system rotates about the axis of the rod, the strings are extended and the tension in the upper string is 80N. A: What is the tension in the lower cord? B: what is the speed of the block? FIGURE: the straight line is the pole. the two angled likes are the strings. each string is 1.25m. the block is 4kg. the distance between the strings on the pole is 2m. | || | | | | | block | | | | || | I drew a horizontal line from the block to the pole and was able to find the angle. this allowed me to find the vertical component of upward tension = 64N. after that i dont know where to go.
