9-9. A projectile is fired at an angle of 45° with initial kinetic energy E,. At the top of its trajectory, the projectile explodes with additional energy E, into two fragments. Öne fragment of mass m, travels straight down. What is the velocity (magnitude and direction) of the second fragment of mass m2 and the velocity of the first? What is the ratio of m/m, when m, is a maximum?
