3 A box rests on top of a flat bed truck. The box has a mass of m= 15 kg. The coefficient of static friction between the box and truck is μ = 0.81 and the coefficient of kinetic friction between the box and truck is HK = 0.66. 1) The truck accelerates from rest to vf = 16 m/s in t = 16 s (which is slow enough that the box will not slide). What is the acceleration of the box? 1 Your submissions: Computed value: 1 Feedback: Correct! m/s² Submit Submitted: Friday, June 9 at 1:22 AM 2) In the previous situation, what is the frictional force the truck exerts on the box? N Submit 3) What is the maximum acceleration the truck can have before the box begins to slide? m/s² Submit 4) Now the acceleration of the truck remains at that value, and the box begins to slide. What is the acceleration of the box? m/s² Submit 5) With the box still on the truck, the truck attains its maximum velocity. As the truck comes to a stop at the next stop light, what is the magnitude of the maximum deceleration the…
