A 2000 N net force will give a car with some amount of mass an acceleration of 4 m/s2
What acceleration will the same net force give a truck whose mass is twice that of the car?

Answer:

2m/s²

Explanation:

Given parameters:

Net force on the car  = 2000N

Acceleration = 4m/s²

Unknown:

Acceleration of a car twice the mass  = ?

Solution:

Let us first find the mass of the car;

 Force  = mass x acceleration

         Mass = [tex]\frac{Force }{acceleration}[/tex]  

 Mass = [tex]\frac{2000}{4}[/tex]   = 500kg

 Now,

     whose mass is twice that of the car

    Mass of the new car = 2 x 500  = 1000kg

So;

  Acceleration  = [tex]\frac{Net force }{mass}[/tex]  

  Acceleration  = [tex]\frac{2000}{1000}[/tex]  = 2m/s²
