(Do not type the unit in your answers) A new
circus act is called the Texas Tumblers. Lovely
Mary Belle swings from a trapeze, projects
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. You can ignore air resistance.
a. What initial speed v, must Mary Belle have
just to reach Joe Bob?
Ans.:
m/s
b. What is the X-component of her velocity when
Mary Belle reaches Joe Bob?
Ans.:
m/s
c. What is the y-component of her velocity when
Mary Belle reaches Joe Bob?
Ans.:
m/s
