A 3 kg box is sliding down a ramp. The friction force up is 2 N.
The ramp has a slope of 10 o above the horizontal. a) Draw a free
body diagram. b) Write the equations for the components of the net
force parallel and perpendicular to the ramp. c) According to
Newton’s laws, what are the parallel and perpendicular components
of the net force on the box? d) What is the acceleration of the
box?
