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 12,000 kg load sits on the flat bed of a 20,000 kg truck moving at 16.0 m/s. Assume that the load is not tied down to the truck, but has a coefficient of friction of 0.525 with the flat bed of the truck.(a) Calculate the minimum stopping distance for the truck 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.)coefficient of friction mass of load mass of truck speed of truck

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
