Unformatted text preview: plate and wall using cables so that its length is l . A block of weight W is given a speed v A when it is at A , and it slides down the incline having a coefficient of kinetic friction k . If it strikes the plate and pushes it forward a distance l 1 before stopping, determine its speed at A . Neglect the mass of the plate and spring. Given: W 4 lb = d 3 ft = l 2 ft = k 50 lb ft = l 1.5 ft = k 0.2 = l 1 0.25 ft = a 3 = b 4 = Solution: atan a b = Guess v A 1 ft s = 265...
