A wagon with a weight of 300 N is accelerated across a level surface at 0.5 m/s2. What net force acts on the wagon? 9.0 N
15 N
150 N
610 N

F = 15.29[m/s²].

Explanation:

To solve this problem we must use Newton's second law which tells us that the force is equal to the product of mass by acceleration.

ΣF =m*a

where:

m = mass [kg]

a = acceleration = 0.5 [m/s²]

Therefore we must find first the mass.

Now replacing in Newton's second law.

the correct answer is b
