A dog sits 1.50m from the center of the merry-go-around and revolves at a tangential speed of 1.80m\s. If the dog’s mass is 18.5kg, what is the magnitude of the centripetal force on the dog? A) 25.53n
B) 32.51n
C) 39.96n
D) 42.55n

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 :

F = centripetal force , N  

m = mass , Kg  

v = linear velocity/tangential  , m/s  

r = radius , m  

Solution

Paraphrase

The magnitude of the centripetal force on the dog : 39.96 N

this is false i think

if it is a true or false question

the answer to your question would be something called hertz. the unit of measurement called a hertz, which is one cycle per second, is used to measure clock speed. within one cycle, your computer processes, refreshes, or updates itself to the changes that it is going through. in the case of computer clock speed, one hertz equals one tick per second. the clock speed of computers is usually measured in megahertz (mhz) or gigahertz (ghz)
