A block with mass m = 0.300 kg is attached to one end of an ideal spring and moves on a horizontal frictionless surface. The other end of the spring is attached to a wall. When the block is at x = +0.240 m , its acceleration is ax = -12.0 m/s2 and its velocity is vx = +4.00 m/s .What is the spring's force constant k ? Express your answer with the appropriate units.
