Question

A model rocket is shot straight up and explodes at the top of its trajectory into three pieces as viewed from above and shown in the figure below. The masses of the three pieces are 

mA = 107.5 g,

 

mB = 20.0 g,

 and 

mC = 30.0 g.

 Immediately after the explosion, piece A is traveling at 1.45 m/s, and piece B is traveling at 7.10 m/s in a direction 30° below the negative x axis as shown. What is the velocity of piece C?

magnitude ? (m/s)
