A new circus act is called the
Texas Tumblers. Lovely Mary
Belle swings from a trapeze, proj-
ects herself at an angle of 53°, and
is supposed to be caught by Joe
Bob, whose hands are 6.1 m above
and 8.2 m horizontally from her
launch point (Fig. P3.66). You
can ignore air resistance. (a)
What initial speed vo must Mary
Belle have just to reach Joe Bob?
(b) For the initial speed calculated
in part (a), what are the magnitude
and direction of her velocity when Mary Belle reaches Joe Bob?
(c) Assuming that Mary Belle has the initial speed calculated in
part (a), draw x-t, y-t, Ux-t, and vy-t graphs showing the motion of
both tumblers. Your graphs should show the motion up until the point
where Mary Belle reaches Joe Bob. (d) The night of their debut per-
