a 35-lb suitcase sits on a rubber ramp at an airport carousel at a 20° angle. the weight vector can be broken into two perpendicular components.

a) what is the magnitude of the component parallel to the ramp surface?

b) what is the magnitude of the component at a right angle to the ramp surface?

c) which of those components is the normal force?

d) which force offsets the kinetic friction force?

e) what happens to the suitcase if Fx exceeds Ff? answer in a brief sentence.

f) what must the coefficient of the static friction be equal or greater to, in order to prevent the suitcase from sliding?
