6.0\,\text{kg}

crate is pulled up a

20^{\circ}

inclined ramp by a rope that exerts a constant

25\,\text{N}

force parallel to the surface. The coefficient of kinetic friction between the crate and ramp is

\mu_k = 0.10

. Determine the magnitude of the crate’s acceleration along the ramp, indicating its direction (up-slope or down-slope). Take

g = 9.8\,\text{m}\,\text{s}^{-2}
