A cannonball is fired with an initial velocity vi of 91.8 m/s, at an angle of θ0 = 57° with the horizontal. At the top of the trajectory, the cannonball explodes into three fragments of masses m1, m2 = m1, and m3 = 2m1. The fragment with mass m3 travels along the +x direction with a speed of 45 m/s. The fragment with mass m1 falls vertically downward with a speed of 48 m/s. Find the magnitude of the velocity of the fragment m2.
(The answer is 120.01 m/s) Just need the steps to get there
