when we have 0 acceleration(constant speed) like a car traveling at a constant speed,
ƒnet=ma
ƒnet=(mobject+mfriction).(aobject+afriction)
let m object be 1500 kg.
m friction be 10 kg
a object be 0
a friction be 20m/s^2
so when we calculate fnet=-20*1600=-32 000 Newtons.
which means wall applies force towards car but the situation isn't like this.
questions:where did I make a mistake?
2-does friction have a mass or acceleration?
