A 2.4 kg toy locomotive is pulling a 1.3 kg caboose. The frictional force of the track on the caboose is 0.46 N backward along the track. If the train is accelerating forward at 3.1 m/s2, what is the magnitude of the force exerted by the locomotive on the caboose(adsbygoogle = window.adsbygoogle || []).push({});

Tried doing 3.7(3.1)+.46=11.93

which equals 12 after sig figs, but it is wrong and I am very confused

Please help, thanks a lot
