A projectile of mass 2.0 kg is fired in the air at an angle of 43.0 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 kg part falls straight down after breakup with an initial speed of 11.6 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 explosion At peak before explosion Vx = (V.x) v = (48.0 m/s)v 43.0 V3,1 = (V3,1) m = 0.3 kg m = 0.7 kg V2,1 = (v2,1) m = 1.0 kg V, f = -(11.6 m/s) Launch (a) Find the speeds (in m/s) of the 0.7 kg and 0.3 kg pieces immediately after the break-up. V = m/s V3 = m/s (b) How high (in m) from the break-up point does the 0.3 kg piece go before coming to rest? m
