    4. max Θ such that mgsinΘ = µmgcosΘ, or Θ = arctan(µ) = arctan(0.67) = 34º

    3. Since 30º < 34º, the block is static and the friction force is equal to the downslope component of gravity, or Ff = mgsin30 = 36kg * 9.8m/s² * sin30º = 176 N

    5. acceleration = gsinΘ - µgcosΘ = 9.8m/s² * (sin37 - 0.57 * cos37) = 1.44 m/s²
