A block is attached to a spring and set in motion on a horizontal frictionless surface by pulling the block back a distance 10cm from equilibrium. Now, replace the block with one double the mass and set the block into motion again by pulling the block a distance 10cm from equilibrium and releasing. How will the following new quantities relate to the quanities with the original block? (If it will be larger by a factor of 2, choose double. sqrt stands for square root.)
Maximum Acceleration
Amplitude
Maximum Force of the Spring on the Block
Period of oscillation

Originally I said that amplitude and max force stay the same, maximum acceleration is doubled, and period is sqrt of 2. It told me I'm wrong. Please help!

consider acceleration, it is dependent on force/mass
you doubled mass, then force same, so acceleration is 1/2
