A block of mass m = 7 kg slides on a rough surface and moves toward a spring with a spring constant k = 1969 N/m, as shown in the figure below. When the block is d 12, 1 m away from the spring, it has a velocity of. At the instant the = block momentarily stops, it has compressed the spring by I = 18 cm. If the coefficient of kinetic friction between the block and the surface below is k 0,4, what is the block's velocity, v =? Provide your answer in units of m/s using one decimal place. Take g = 9.80 m/s. m v k 0 0 0 0 0 0 0 0 0 0 0 d X
