Astrophysics question: Are zero braking distance collisions and infinitive forces possible?

Description : Astrophysics question: Are zero braking distance collisions and infinitive forces possible?

Last Answer : No, it is not. F=m*a, where a is acceleration expressed in m/s/s. zero braking distance also means zero deceleration time. deceleration is negative acceleration. So zero deceleration time turns it into m/s/0. Division by zero.

Stopping distance of vehicles : When brakes are applied to a moving vehicle, the distance it travels before stopping is called stopping distance.
