The cue ball hits the "8" ball in a head-on collision. The cue ball is moving at a speed of 3.96 m/s before collision while the "8" ball is at rest. What is the speed of the "8" ball after collision? Assume the billard balls are identical and the collision is perfectly elastic. Express your answer in m/s and with two decimal places.

A ball named "Exploding kitten" initially at rest suddenly explodes into two parts. One, with mass of 1.58 kg has a resulting speed of 9 m/s relative to its original position. The other mass is moving at a speed of 10.3 m/s. What is its mass? Express your answer in two decimal places with units of kg.
