When two male rams fight each other for a
female, their heads hit each other with
tremendous force. In physics, when an
object slows down, it is called "deceleration"
or negative acceleration (opposite of
speeding up). When rams make contact,
each ram's head is subjected to -8.6 m/s2
(read that as meters per second per second)
acceleration. If they fight long enough to hit
each other 9 times, what is the total
acceleration experienced by each ram? Is it
(+) or (-)?
