Amber applies a net force of 35 N to pull her younger brother (32 kg) in a wagon (3 kg). at what rate does the wagon accerlerate
Ket [755]

Answer:

C. 1.00 m/s^2

Explanation:

We can solve the problem by using Newton's second law:

F=ma

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

m=32 kg+3 kg=35 kg

Therefore, we can re-arrange the previous equation to find the acceleration:

a=\frac{F}{m}=\frac{35 N}{35 kg}=1.00 m/s^2
