A 25-N net force is applied to a rolling cart and produces an acceleration of 5 m/s2 . What is the cart’s mass?

5kg

Explanation:

Given parameters:

Force = 25N

Acceleration  = 5m/s²

Unknown:

Mass of cart  = ?

Solution:

Based on newton's second law of motion;

    Force  = mass x acceleration

Now to find the mass;

     Mass  =

   Now insert the parameters and solve;

   Mass =  = 5kg
