Shown to the right is a block of
mass m = 14.4 kg sitting on a ramp
that makes an angle θ = 21° with the
horizontal. This block is being pushed by a horizontal
force F = 223 N. The coefficient of
kinetic friction between the two surfaces
is μ = 0.47.
Write an equation for the acceleration of the block up the ramp
using variables from the problem statement together
with g for the acceleration due to
gravity.
Find the acceleration of the block up the ramp in
m/s2.
