A 6.2 kg model rocket is traveling horizontally and due south with a speed of 20.3 m/s when it explodes into two pieces. The velocity of one piece, with a mass of 1.6 kg, is

Question

v1 = (-12 m/s)i + (30 m/s)j + (15 m/s)k,

with i pointing due east, j pointing due north, and k pointing vertically upward.

(a) What is the velocity of the other piece, in unit-vector notation?
m/s i
m/s j
m/s k
(b) What is the kinetic energy of the other piece?
J
(c) How much kinetic energy is produced by the explosion?
J
