A block of mass m = 3.5 kg slides on a horizontal rough surface head on into a spring of spring constant k 378 N/m, as shown in Figure. When the block is x = 1 meter away from the spring, it has a velocity v = 4.47 m/s. When the block stops, it has compressed the spring by 9.1 cm. What is the coefficient kinetic friction between the block and the surface? Provide your answer with 2 decimal places. Take g = 9.81 m/s? V
