Chapter 9, Problem 55P

A projectile of mass 2.0 kg is fired in the air at an angle of $\text{4}0.0°$ 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 moves in the original forward direction, and the 0.3-kg part goes straight up.

Launch

a. Find the speeds of the 0.3-kg and 0.7-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?
