To find the magnitude of the centripetal force on the dog, we can use the formula for centripetal force:
where:-
is the mass of the dog,-
is the tangential speed of the dog,-
-
-
Substituting these values into the formula:
First, calculate the tangential speed squared:
Next, multiply this by the mass of the dog:
Finally, divide by the radius:
Therefore, the magnitude of the centripetal force on the dog is approximately
.
