A firecracker in a coconut blows the coconut into three pieces. Two pieces of equal mass fly off south and west, perpendicular to each other, at 20 m/s. The third piece has twice the mass as the other two. What is the speed of the third piece? What is the direction of the third piece? GIve the direction as an angle east of north.
