A block of mass m slides on a rough surface and moves toward a spring with a spring constant 3538 N/m, as shown in the figure below. When the block is d = 16, 9 m away from the spring, it has a velocity of v = 18, 7 m/s. When the block momentarily stops, it has compressed the spring by x = 39 cm. If the coefficient of kinetic friction between the block and the surface below is Mk 0, 41, what is the mass of the block, m=? Provide your answer with one decimal place. Take g = 9.80 m/s. k = = m V k mmmmmmmm d x
