44. We assume there are no forces or forcecomponents along the
x
direction. We
combine Eq. 2228 with Newton’s second law, then use Eq. 421 to determine time
t
followed by Eq. 423 to determine the final velocity (with –
g
replaced by the
a
y
of this
problem); for these purposes, the velocity components
given
in the problem statement are
relabeled as
v
0
x
and
v
0
y
respectively.
