A 25.0-N force is applied to a 5.0-kg object to accelerate is rightwards. The object encounters 15.0-N of friction. Determine the acceleration of the object. (Neglect air resistance.) show your work below.

Answer: The acelaration is 2 m/s^2

Explanation: Using the second Newton law

The total force acting over the object is equal to the mass x accelaration, that is:

We considerer the applied force to the object equal to 25N

and the friction force of 15 N

25N-15N = m*a
