Question

In a science fiction novel two enemies, Bonzo and Ender, are fighting in outer spce. From stationary positions, they push against each other. Bonzo flies off with a velocity of +1.8 m/s, while Ender recoils with a velocity of -2.6 m/s. Determine the ratio mBonzo/mEnder of the masses of these two enemies.

Answer 1

Step-by-step explanation:

Conservation of momentum

Initial momentum is zero

mB(1.8) + mE(-2.6) = 0

mB(1.8) = mE(2.6)

mB/mE = 2.6/1.8
