Answer:
39.96 N
Further explanation:
Given
radius=R=1.5 m
Tangential speed =v=1.80m\s
mass of the dog=18.5 kg
Required
The magnitude of the centripetal force
Analysis
Use Centripetal force formula :
[tex]]\large{\boxed{\bold{F= \frac{mv^2}{R}}}[/tex]
F = centripetal force , N
m = mass , Kg
v = linear velocity/tangential , m/s
r = radius , m
Solution
[tex]\tt F=\dfrac{18.5\times 1.8^2}{1.5}\\\\F=39.96~N[/tex]
Paraphrase
The magnitude of the centripetal force on the dog : 39.96 N
