Question

Image for A cherry bomb explodes into three pieces of equal mass. One piece has an initial velocity of 11m/s x. Another

What is the velocity of the third piece?

science physics

Answer 1

Answer #1

Since the cherry bomb has an initial momentum of 0 its final momentum must also be 0

there

solving x momentum

mv = 0

11 + 8 + vx = 0

vx = -19m/s

then for the y momentum

-4 + vy = 0

vy = 4 m/s

so the velocity of the third piece is

v3 = -19 x + 4 y
