Question
A block of mass m = 0.9 kg slides on a horizontal rough surface head on into a spring of spring constant k, as
shown in Figure. When the block is x = 1.2 meter away from the spring, it has a velocity v = 4.7 m/s. When the
block stops, it has compressed the spring by 13.7 cm. The coefficient of kinetic friction between the block and
the surface is 0.33. What is the value of the spring constant k in N/m? Provide your answer with 0 decimal
places.
