A block of mass $0\mathrm{.}5$ kg is hanging on the end of a spring that is attached to a ceiling. The spring has a spring constant of $12\mathrm{.}5$ N$/$m$.$ The block is then pulled $0\mathrm{.}3$m below its static equilibrium position and released from rest.

 $($a$)$ How long will it take for the block to have an downward acceleration that is $1/3$ of its maximum acceleration, $$

$($b$)$ What is the velocity of the block at that time, and $$

$($c$)$ Where is the block at that time? 

Answer rating: 100% (QA)

To solve this problem we need to consider the motion of the block as it oscillates up and down after being released from rest Given Mass of the block ... View the full answer
