A 0.5 kg block is attached to a spring of force constant 8 . The block is pulled 4 cm to the left of equilibrium and released from rest. The block begins to move back towards equilibrium (x = 0). Find the speed of the block at x = 1 cm if the horizontal surface is frictionless. Round answer to the hundredths place and be sure to include the units. Be sure to put a space between your numerical answer and the unit symbol. Answer: The speed is [speed].
