What is her average acceleration from 0 to 9.0 seconds?

0.863333

86%

hope this

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

hope that !                                         : )

be subject to a force andchange its motion

wavelength divides in half and speed stays the same.
