A 18.5 kg ball is thrown at an angle of 49° above the horizontal off of a building such that its initial potential energy is 449 J, and the initial kinetic energy is 458 J.

Once the ball is flying in its arc, what will be the potential energy of the ball when the kinetic energy is 71.1 J?

In atoms, the electron carries a negative elementary or unit charge; the proton carries a positive charge. the two types of charge are equal and opposite. in an atom of matter, an electrical charge occurs whenever the number of protons in the nucleus differs from the number of electrons surrounding that nucleus.
