It then continues to slide along the horizontal rough surface until it strikes the spring. Determine how far it compresses the spring before stopping. Given: W 5lb = k 0.2 = a 3f t = 90 deg = b 2f t = k 40 lb ft = Solution: Guess d 1f t = Given Wa k Wb d + 1 2 kd 2 0 = d Find d = d 0.782 ft = * Problem 14-24 The block has a mass M and moves within the smooth vertical slot.
