Answer:
the object will fall 792 feet in 17 seconds
Step-by-step explanation:
first you can do 144 multiplied by 5 because that would be 15 of those seconds next you would do 144 divided by 2 because you only need 2 seconds to reach 17 your answer would be 72 then you would do 720+72=792 so it would fall 792ft in 17 seconds

I think it is the second option
The complete question in the attached figure
we know that
radius r of a circle=4 units
in the triangle OST
OT=OS=4 units
m∠OST = 60°
cos 60°=(ST/2)/r-------> ST=2*r*cos 60°-----> 2*4*(1/2)----> 4 units
so
triangle OST
<span>it's an equilateral triangle
</span>
the answer Part a) is ST=4 units
Part b)
Find PT
in the triangle POT
m∠POT = (180°-60°)---------> 120°
m∠OTP = 30°
cos 30°=(PT/2)/r------> PT=2*r*cos 30°------> 2*4*√3/2----> 4√3 units
the answer Part b) isPT=4√3 units
