Answer:
C. 1.00 m/s^2
Explanation:
We can solve the problem by using Newton's second law:
[tex]F=ma[/tex]
where
F is the net force acting on an object
m is the mass of the object
a is its acceleration
In this case, the net force applied by Amber is F=35 N, while the total mass of the brother+the wagon is
[tex]m=32 kg+3 kg=35 kg[/tex]
Therefore, we can re-arrange the previous equation to find the acceleration:
[tex]a=\frac{F}{m}=\frac{35 N}{35 kg}=1.00 m/s^2[/tex]
