The only way for the force in the frame of reference of the car to add up to zero is if there is an additional force, →FI, that is exerted in that frame of reference: \[\begin{aligned} \sum \...The only way for the force in the frame of reference of the car to add up to zero is if there is an additional force, →FI, that is exerted in that frame of reference: ∑→F=→T+→Fg+→FI=0(car reference frame) Since we know that →T+→Fg=m→a, we can substitute this in the equation above: \[\begin{aligned} \sum \vec F &= \vec T + \vec F_g + \vec F_I =0\quad\quad\text{(car reference frame)}\\ &=m\…
