A 1.81-kg juggling ball is thrown with a kinetic energy of 4.00 J. It then hits a wall and comes back a with half its original speed. The ball's kinetic energy after hitting the wall must be J. Round your answer to three significant figures.

i don’t know what the answer is i wish i

another example of kinetic energy would be,

kinetic energy   >     moving energy
