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 40.0 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 10.0 m/s, the 0.7 kg part moves in the original forward direction, and the 0.3 kg part goes straight up. (a) Find the speeds (in m/s) of the 0.7 kg and 0.3 kg pieces immediately after the break-up? (b) How high 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? (Give the horizontal distance in meters from the launch point to where the 0.7 kg piece lands.)

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 40.0 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 10.0 m/s, the 0.7 kg part moves in the original forward direction, and the 0.3 kg part goes straight up.

(a) Find the speeds (in m/s) of the 0.7 kg and 0.3 kg pieces immediately after the break-up?

(b) How high 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? (Give the horizontal distance in meters from the launch point to where the 0.7 kg piece lands.)

55. A projectile of mass 2.0 kg is fired in the air at an
angle of 40.0° to the horizon at a speed of 50.0 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
10.0 m/s, the 0.7-kg part moes in the original forward
direction, and the 0.3-kg part goes straight up.
