If the collision is elastic, there is no loss in kinetic energies, which means that the total energies before and after impact are the same. So no need to worry about final velocities.
Final energy
= initial energy
= (1/2) (7.20*2.00^2+5.75*(-1.30)^2)
=19.26 joules
Answer: the total kinetic energy is 19.3 J. after collision.
D oxygen i believe is your answer
Longitudinal wave hope this is right :))))))))))
Answer:
most of the time the bullet will not hurt you but sometimes can hurt or kill you.
It would be Newton’s second law of motion
