A bicyclist of mass 68 kg rides in a circle at a speed of 3.9 m/s. If the radius of the circle is 6.5 m, what is the centripetal force on the bicyclist?

A. 41 N
B. 159 N
C. 179 N
D. 92 N

Answer :

Data:
Centripetal Force = ? (Newton)
m (mass) = 68 Kg
s (speed) = 3.9 m/s
R (radius) = 6.5 m

Formula:
[tex] F_{centripetal\:force} = \frac{m*s^2}{R} [/tex]

Solving:
[tex] F_{centripetal\:force} = \frac{m*s^2}{R} [/tex]
[tex]F_{centripetal\:force} = \frac{68*3.9^2}{6.5}[/tex]
[tex]F_{centripetal\:force} = \frac{68*15.21}{6.5}[/tex]
[tex]F_{centripetal\:force} = \frac{1034.28}{6.5}[/tex]
[tex]\boxed{\boxed{F_{centripetal\:force} = 159.12\:N}}[/tex]
