A block of mass m = 8,9 kg slides on a rough surface and moves toward a spring with a spring constant k = 1004 N/m, as shown in the figure below. When the block is d = 13,1 m away from the spring, it has a velocity of v. At the instant the block momentarily stops, it has compressed the spring by x = 27 cm. If the coefficient of kinetic friction between the block and the surface below is k = 0,45, what is the block's velocity, U =? Provide your answer in units of m/s using one decimal place. Take g = 9.80 m/s. m V d k mmmmmmm X
