Consider a large truck carrying a heavy load, such as steel beams.A significant hazard for the driver is that the load may slideforward, crushing the cab, if the truck stops suddenly in anaccident or even in breaking. Assume, for example, that a 9000 kgload is located on the flat bed of a 25000 kg truck moving at 15.0m/s. Assume the load is not tied down to the truck and assume thatthe coefficient of friction between the load and the truck bed is0.600.
(a) Calculate the minimum stopping distance for the truck for whichthe load will not slide forward relative to the truck.
______m
(b) Is any piece of data unnecessary for the solution? (Select allthat apply.) (Below)
-speed of truck
-mass of load
-coefficient of friction
-mass of truck
