6. Jamal is at Six Flags playing at the arcade. At one booth he throws a 0.50 kg ball forward with a velocity of 21.0 m/s in order to hit a 0.20 kg bottle sitting on a
shelf, and when he makes contact the bottle goes flying forward at 30.0 m/s
a. What is the velocity of the ball after it hits the bottle?
b. If the bottle were more massive (but flew forward with the same final velocity),
how would this affect the final velocity of the ball?

Will give brainliest! which statement best describes the similarities between fundamental forces? electromagnetic and strong nuclear forces influence the interaction between charged particles within an atom. gravitational and magnetic forces are both types of charges that occur in nature. nuclear and magnetic forces are both related to mass and weight. strong nuclear force is most like electrical force because they are both related to distance.
