Block $1$ on the left is connected to block $2$ on the right by a cable that is $20\backslash$deg from the horizontal. Block $2$ is also connected to the wall on its right by a horizontal cable with a tension of $85\mathrm{.}0$ N. The surfaces are smooth. The mass of block $2,$ m$2=5\mathrm{.}00$ kg$.$

a$.$ Draw the FBD for each block, and clearly indicate your choice of coordinate axes for each.

b$.$ For each block, write out Newton$’$s $2$nd Law, decomposed based on your choice of coordinates.

c$.$ Solve for the mass of block $1,$ the normal force on block $1$ due to the $55\backslash$deg ramp, and the normal force on block $2$ due to the $8\backslash$deg ramp.
