How Do Rotating Reference Frames Affect Forces on a Merry-Go-Round?

[jimmy.dude]

Looking down from a stationary tree branch, a merry-go-round spins in a counterclockwise
direction with an angular velocity of 1 radian per second. a squirrel of mass 0.2 kg sits on the outer rim of the merry-go-round, at a radius of 2.0 meters.

a) what is the magnitude and direction of the vector omega

b) What is the magnitude and direction of the Coriolis pseudo-force as felt by the squirrel?
(possible equation: -2m(omega x v_r)

c)What is the magnitude and direction of the centrifugal pseudo-force as felt by the squirrel?
(possible equation: -m(omegax(omegaxr_r)

I have no idea where to start!

your answer to part a is correct, but for part b,it is not.

For part b, your equation is OK, but what is v_r of the squirrel?

For part c, your magnitude is correct, but you need to explain what is meant by the minus sign regarding the direction of the pseudo centrifugal force.
