Unformatted text preview: meters), before it hits the ground? (Use the x origin as the point of launch, and use g = 9.81 m.s-2 .) Unfortunately, immediately after the launch, the object explodes into two fragments (each of mass equal to one-half of the original object (m 1 = m 2 = m /2 = 15 kg) i.e. we are neglecting the mass of the explosive material). The explosion contributes an additional energy of E ex = 10.0 kJ (10000 Joules). The two fragments are ejected at right angles to the original line of flight of the initial object i.e. vertically in the CM frame, fragment m 1 straight up and fragment m 2 straight down. (c)  Immediately after the explosion, what is the velocity (magnitude and angle relative to the horizontal) of fragment m 1 relative to an observer on the ground?...
