Shown in the figure below is a block and track system. All locations indicated by solid black lines are frictionless. The region indicated by the tan hash is a patch of friction with coefficient uk = 0.380 whose length is d = 1.45 meters. A small block of mass m = 0.89 kg is initially at moving toward the right with a velocity of v1 = 6.899 meters/second. The mass rises up the hill of height y2 = 0.60 meters, passes across the frictional region and then compresses the spring which has a spring constant of k = 126.3 N/m. XA=? V, =? V3= ? 4 2 friction 3 m Y2 d Calculate all the following: The velocity of the mass at the top of the hill, v2 = m/s The velocity of the mass after the frictional area, V3 = m/s The maximum compression of the spring, X4 = meters
