Answers: (6) 23.8, (10) 0.34
Explanation:
(6) Find the circumference (C):
C = 2πr
= 2π(3.79 meters)
= 7.58π meters
= 23.8 meters
(10) Find the centripetal acceleration (a):
C = 2πr
6 = 2πr
[tex]\frac{6}{2\pi}[/tex] = r
[tex]\frac{3}{\pi}[/tex] = r
a = [tex][tex]\frac{v^{2}}{d/2}[/tex][/tex]
= [tex]\frac{(0.57meters/second)^{2}}{3/\pimeters}[/tex]
= [tex]\frac{0.57^{2}}{3/\pi}m/s^{2}[/tex]
= 0.34 m/s²
