During a heated game of bocce ball, Ursula is attempting to knock the pallino (the small, white target ball) away from where her opponent's balls lie on the ground. She can do this by throwing her ball so that it lands directly on top of the pallino, which is
x=17 m
horizontally downcourt from where she throws. If she releases the ball
y=0.90 m
above the ground at an angle of
θ=23
∘

above the horizontal, then how much time will the ball spend airborne before hitting the pallino? Both balls may be treated as point particles in this problem.
