Answer:
The force will be [tex]F_{c}=2.47 N[/tex]
Explanation:
Let's use the centripetal force equation.
[tex]F_{c}=m\omega ^{2}R[/tex]
Where:
m is the mass of the bunch of bananas
ω is the angular speed
R is the radius
Now, 1 rev every 4 seconds or 0.25 rev/sec is the angular speed, but we need to write this speed in rad per second.
[tex]\omega =0.25\frac{rev}{s}=0.25*2\pi \frac{rad}{s}=1.57 \frac{rad}{s}[/tex]
FInally, the force will be:
[tex]F_{c}=2.0*1.57^{2}*0.5[/tex]
[tex]F_{c}=2.0*1.57^{2}*0.5[/tex]
[tex]F_{c}=2.47 N[/tex]
I hope it helps you!
