At the county fair, chris throws a 0.12kg baseball at a 2.4kg wooden milk bottle, hoping to knock it off its stand and win a prize. the ball bounces straight back at 30% of its incoming speed, knocking the bottle straight forward. what is the bottle's speed, as a percentage of the ball's incoming speed? express your answer using two significant figures.

Explanation:

= Mass of ball = 0.12 kg

tex]m_{2}[/tex] = Mass of bottle = 2.4 kg

= Initial velocity of ball

= Initial velocity of bottle

= Final velocity of ball =

= Final velocity of bottle

As linear momentum is conserved

The bottle's speed is

a

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.
