Question

The driver of the truck suddenly applies the brakes and the truck comes to a stop. During braking, either the crate slides or does it not. Considering the forces acting on the truck during braking, will the truck stop in shorter distance (time) if the crate slides, or will the distance (or time) be shorter if it does not?

Answer 1

As we know,

Force = Mass * Acceleration

Here, the mass is remaining constant irrespective of the position of objects.

As the same force is being applied to the same mass. So, the stopping distance will be the same irrespective of the crate slides or not.
