Let
be the bus path and
be the jodis path.
(a)
\The position
at time
of an object having acceleration
is
.
The acceleration of the train is
.
Jodi can run with a speed of
.
Train:
\
.
.
Jodi:
\
.
.
(b)
\Jodi will catch the train if
.


.
Find
.
.
Since
, the equation has no real solution.
Thus, jodi will not catch the bus.
\(c)
\Graph the parametric equations
,
,
and
.
.
