A projectile of mass 2.0 kg is fired in the air at an angle of 45.0° to the horizon at a speed of 48.0 m/s. At the highest point in its flight, the projectile breaks into three parts of mass 1.0 kg, 0.7 kg, and 0.3 kg. The 1.0 kgpart falls straight down after breakup with an initial speed of 11.2 m/s, the 0.7 kg part moves in the original forward direction, and the 0.3 kg part goes straight up.At peak after explosionV3,1 = (V3,)Îm3 = 0.3 kgAt peak before explosionm2 = 0.7 kg(Vix)îV21 = (V2,)î%3Dv; = (48.0 m/s)v;m1 = 1.0 kgV1, f = -(11.2 m/s)ĵ45.0°Launch(a) Find the speeds (in m/s) of the 0.7 kg and 0.3 kg pieces immediately after the break-up.V2m/s%DV3m/s(b) How high (in m) from the break-up point does the 0.3 kg piece go before coming to rest?(c) Where does the 0.7 kg piece land relative to where it was fired from?
