*Neglect the friction between the car and the earth, but not the friction between the stuff inside the car & the interior surface of the car*
For example, if we're moving with a car at constant speed and we used the brake to stop with constant acceleration, and the stuff inside the car included...
I know what you mean, but there are two masses, if we simply put them at one end it'd read 98 N, and now by putting one at every end it will read 48 N, I just can't understand why :/

This set is in equilibrium and I can't find out what will the scale write down in Newtons, any help?
