(a) A flatbed truck moving at 28 m/s carries a steel girder that rests on its wooden floor. The girder is notstrapped down, in violation with USDOT regulations. If the coefficient of static friction between steel andwood is 0.52, what is the minimum distance over which the truck can come to a stop without the girdersliding toward the cab of the truck? (answer: 77 m)(b) What is the minimum time over which the truck can accelerate forward from 0 m/s to 28 m/s with aconstant acceleration without the girder sliding off the back? (answer: 5.5 s)FNET = mafs,max = UsNW =mgv² = vo² + 2aAx%3D%3DV = Vo+ atg = 9.81 m/s?

In about 1915, Henry Sincosky of Philadelphia suspended himself from a rafter by gripping the rafter with the thumb of each hand on one side and the fingers on the opposite side. Sincosky’s mass was 79 kg. If the coefficient of static friction between hand and rafter was 0.70, what was the least magnitude of the normal force on the rafter from each thumb or opposite fingers? (After suspending himself, Sincosky chinned himself on the rafter and then moved hand-over-hand along the rafter. If you do not think Sincosky’s grip was remarkable, try to repeat his stunt.)
