Question

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?

Answer 1

Answer:

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.

$W =m*g\\m=W/g\\m = 300/9.81\\m = 30.58 [kg]$

Now replacing in Newton's second law.

$F = m*a\\F = 30.58*0.5\\F=15.29[m/s^{2}]$
