2012 F = ma Exam — Question 8

8. A block of mass m = 3.0 kg is moving on a horizontal surface towards a massless spring with spring constant k = 80.0 N/m. The coefficient of kinetic friction between the block and the surface is µk = 0.50. The block has a speed of 2.0 m/s when it first comes in contact with the spring. How far will the spring be compressed?
