A projectile with a mass of m = 10 kg had a speed of v = 300 m/s at the top point of the trajectory. At this point it broke into two parts. The smaller one with mass m1 = 2 kg received a speed u1 = 500 m/s. At what speed and in what direction will the larger part fly if the smaller one flies forward at an angle α = 60° to the horizontal plane?
