An object is thrown downward at 42.8 m/s off of a 324 m tall building . find its final velocity immediately before hitting the ground Need help with this question rq please

y=x+9

?

step-by-step explanation:

i think the answer is b

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
