While riding in a hot air balloon, which is steadily descending at a speed of 2.44 m/s, you accidentally drop your cell phone. (a) After 4.00 s, what is the speed of the cell phone?
V = 41.64
m/s
(b) How far is the cell phone below the balloon after this time?

another example of kinetic energy would be,

kinetic energy   >     moving energy

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