Question: A small block is attached to an ideal spring and is moving in SHM on a horizontal, frictionless surface. When the block is at x= 0.270 m , the acceleration of the block is -5.67 m/s2. What is the frequency of the motion? The response must be typed, single spaced, must be in times new roman font (size 12) and must follow the APA format.
