A 60-kg person on a merry-go-round is traveling in a circle with a radius of 3 m at a speed of 3 m/s

a) what is the magnitude of the acceleration experienced by this person?
9/3=3m/s2

B) what is the magnitude of the net force experienced by this person?

F= m x ac
Fc= 60(3)= 180

or this equation

vfy=voy+at

Which equation should be used for B...I'm not sure

this one

the other equation is invalid since acceleration is not constant

Re: Help with physics
ok this equation is the one I use right? F= m x ac
