Answer:
The acceleration of Abbie is half of the Zak's.
Explanation:
The centripetal acceleration of an object on a circular path is given by :

Two children are riding on a merry-go-round that is rotating with a constant angular speed. Let
is distance of Abbie from the merry-go-round and
is distance of Zak's from the merry-go-round. Acceleration of Abbie is :
...... (1)

Acceleration of Zak's is :
.......(2)

Dividing equation (1) and (2) we get :

So, the acceleration of Abbie is half of the Zak's.
Answer:
Magnitude F(t)=26.6 N
Direction: -x
Explanation:
Given data
Spring constant K=4.77 N/m
Mass m=1.89 kg
Displace A=5.56m
Time t=3.96s
To find
Magnitude of force F
Solution
The angular frequency is given as

Force on object is

Substitute given values
So

So
Magnitude F(t)=26.6 N
Direction: -x
