An initially stationary object sitting at the origin explodes into exactly two pieces. Piece 1 flies off with velocity 2m/s to the north and piece 2 flies off with speed 5m/s. Part a (1 points) In which direction does Piece 2 fly? Select the correct answer O Could be any direction. The direction of its motion is undefined. O East South Your Answer O West O NorthPart b What is the ratio of the masses for the two pieces (m1 : m2)? Part c What is the ratio of the kinetic energies for the two pieces (KE] : KE2)?Part cl (1 points) What is the position (relative to the origin) of the center of mass for the two pieces exactly 5.6sec after the explosion? Assume values to the north are positive
