and gravity due it is a constant
b) The maximum high reached by the dolphin is
c) Total time is
Explanation:

b) Second, now that we know final speed we use , as we clear for
.
Then we use
c)Third, finally we can use , as we know
when the dolphin fall into the water again and
, then we have
is a quadratic form
