Consider a block with a mass of 800 g sitting on a frictionless floor. Opposite ends are attached to relaxed springs, which are each attached to a wall. Let K1 = 400 N/m be the spring constant of the spring on the left and k2 = 300 N/m be the spring constant of the spring on the right. If the object is displaced to the right of its equilibrium point by 30 cm and then released, what is the initial acceleration (magnitude and direction) of the object?
