$11\%)$ Problem $7$: A spring with a spring constant of k $=177$N $/$ m is initially compressed by block a distance d $=0\mathrm{.}2$ deg m from its unstretched length. The block is on a horizontal surface with coefficients of static and kinetic friction mu$\_\{$s$\}$ and mu$\_\{$k$\}$ and has a mass of m $=7$kg Refer to the figure

Part a $$ The block is released from the initial position and begins to move to the right and turn expression for the sum of the forces in the next direction the configuration shown above in terms of define quantities and g$.$ EFx equals$?$

$33\%$ Part $($a$)$ The block is released from the initial position and begins to move to the right. Enter an expression for the sum of the forces in the $x-$direction in the configuration shown above, in terms of defined quantities and $g.$

$33\%$ Part $($b$)$ Calculate the smallest value for the coefficient of static friction ${}_s$ that would keep the block from moving.

$33\%$ Part $($c$)$ Assuming the block has just begun to move and the coefficient of kinetic friction is ${}_k=0\mathrm{.}2,$ what is the block's acceleration in meters per second

$$Part B Calculate the smallest value for the coefficient of the statistics friction you line us that would keep the block from moving

parts c$.$ assuming the block has just begun to move in the coefficient of kinetic friction is UK equals $0\mathrm{.}2$ what is the blocks acceleration in meters per second squared$?$
