A schematic diagram showing a horizontal mass-spring oscillator on a flat surface. On the left, a vertical wall has diagonal hatching along its left edge to indicate a fixed boundary. Extending horizontally from the wall to the right is a coiled wire spring with several evenly spaced turns. The right end of the spring is attached to the left face of a solid rectangular block resting on a horizontal ground line. The block is labeled with the uppercase letter \( M \) in its center. The horizontal ground line extends beneath the wall and block. No other labels, arrows, dimensions, coordinate axes, or text appear.
A block of mass M attached to a horizontal spring.
A block of mass \( M \) is attached to an ideal horizontal spring of spring constant \( k \) on a frictionless horizontal surface. When displaced from equilibrium and released, the block oscillates with period \( T_0 \). If the block is replaced by a block of mass \( 4M \) attached to the same spring and set into oscillation, what is the new period of oscillation in terms of \( T_0 \)?
