Block $A$ is released from rest and starts sliding down the incline with an acceleration $a_O=3\mathrm{.}9\frac{m}{s^2}.$ Determine the acceleration of

block $B$ relative to the incline. Also, determine the time needed for $B$ to move a distance $d=0\mathrm{.}2m$ relative to $A.$

The acceleration of block $B$ relative to the incline is

hat$(i)\frac{m}{s^2}.($Round the final answer to one decimal place, Include a minus

sign if necessary$)$

The time needed for $8$ to move a distance is

$($Round the final answer to four decimal places.$)$
