Consider a large truck carrying a heavy load, such as a steel beam. 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 10000 kg load is located on the flatbed of a truck moving at 12.0 m/s. Assume the load is not tied down to the truck and assume that the coefficient of friction between the load and truck bed is 0.500. Calculate the minimum stopping distance for the truck, at which the load will not slide forward relative to the truck.

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

A crate of mass 45.0 kg is being transported on the flatbed ofapickup truck. The coefficient of static friction between thecrateand the truck's flatbed is 0.350, andthe coefficient ofkinetic friction is 0.240.

(a) The truck accelerates forward onlevelground. What is the maximum acceleration the truck can have sothatthe crate does not slide relative to the truck's flatbed?
1 m/s²

(b) The truck barely exceeds this acceleration and then moveswithconstant acceleration, with the crate sliding along its bed.Whatis the acceleration of the crate relative to the ground?
2
Your response differs from the correct answerby 10% to 100%.m/s²
