8. john has to hit a bottle with a ball to win a prize. he throws a 0.4 kg ball with a velocity of 18 m/s. it hits a 0.2 kg bottle, and the bottle flies forward at 25 m/s. how fast is the ball traveling after hitting the bottle?

The velocity of the ball the ball after collision is 5.5 m/s.

Explanation:

John hitting the bottle which is at rest means this is an Elastic collision.

Mass of the ball=

Velocity of ball before collision =

Velocity of ball after collision =

Mass of the bottle=

Velocity of bottle before collision = (bottle is at at rest)

Velocity of bottle after collision =

The velocity of the ball the ball after collision is 5.5 m/s.

explanation:

areas w steep slopes, west coast, rocky mountains, and appalachian mountains

the inner core.

good luck: )
