A train consists of a 4300-kg locomotive pulling two loaded boxcars. The first boxcar (just behind the locomotive) has a mass of 12,700 kg and the second (the car in the back) has a mass of 16,300 kg. Presume that the boxcar wheels roll without friction and ignore aerodynamics. The acceleration of the train is 0.569 m/s2. (a) With what force, in Newtons, do the boxcars pull on each other

To solve this problem we will apply the concepts related to Newton's second law, which defines force as the product between mass and acceleration. Mathematically this can be described as,

[tex]F = ma[/tex]

Here,

m = Mass

a = Acceleration

Taking as reference the mass of the second boxcar, the force applied would be

[tex]F = m_2 a[/tex]

[tex]F = (16300kg)(0.569m/s)[/tex]

[tex]F = 9274.7N[/tex]

Therefore the boxcars pull on each other with a force of 9274.7N
