Wally and Luke advertise their circus act as "The Human Burrs---Trapeze Artists for the New Millennium." Their specialty involves wearing padded Velcro suits that cause them to stick together when they make contact in midair. While working on their act, Wally is shot from cannon with a speed of 20 m/s at an angle of 30° above the horizontal. At the same moment, Luke drops from a platform having (x, y) coordinates of (8 m, 16 m), if the cannon is taken to sit at the origin. 

(a) Will they make contact? 

(b) What is the minimum distance separating Wally and Luke during their flight paths? 

(c) At what time does this minimum separation occur? 

(d) Give the coordinates of each daredevil at that time.
