I drop a meter stick from 8 meters off the ground. Please explain clearly. thank you

Problem 3 ( a ) I drop a meter stick from & meters off the ground ( as illus trated to the right ) . At time to , the stick is released dropping a distance of lot units in t seconds . Simultane ously the stick is rotating clockwise at constant speed about its centre , rotating once every two seconds . Find a family of affine transformation It ( * ) which maps the stick from its starting position to its position at time to ( b ) At what time does the meter hit the ground ? Given an approximate answer to 3 decimal places . ( Hint : Use the diagram to figure out what part hits the ground first . Once you get an equation for t find a method that approximates a solution . )
