A block of mass m = 3.9 kg slides on a horizontal rough surface head on into a spring of spring constant k = 370 N/m, as shown in Figure. When the block is x = 1.4 meter away from the spring, it has a velocity v. When the block stops, it has compressed the spring by 5.5 cm. The coefficient of kinetic friction between the block and the surface is 0.15. What is the block's velocity v (in m/s)? Provide your answer with 2 decimal places. Take g = 9.81 m/s2
