Aprojectile of mass 2.75 kg is fired in the air at an angle of 45.0^\circ45.0 ∘ to the horizon at a speed of 290.0 m/s. at the highest point in its flight, the projectile breaks into three parts of mass 2.00 kg, 0.70 kg, and 0.05 kg. the 2.00 kg part falls straight down after breakup with an initial speed of 10.0 m/s, the 0.70 kg part moves in the original forward direction, and the 0.05 kg part goes straight up. find the speeds of the 0.7 and 0.05 kg pieces immediately after the break-up
