Consider a large truck carrying a heavy load, such as steel beams. a significant hazard for the driver is that the load may slide forward, crushing the cab, if the truck stops suddenly in an accident or even in braking. assume, for example, that a 14,000-kg load sits on the flatbed of a 20,000-kg truck moving at 12.0 m/s. assume the load is not tied down to the truck and has a coefficient of static friction of 0.400 with the truck bed.

(a) calculate the minimum stopping distance for which the load will not slide forward relative to the truck.
m

(b) is any piece of data unnecessary for the solution? (select all that apply.)
mass of the load
mass of the truck
velocity
coefficient of static friction
all are necessary

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
