You pull your 18-kg suitcase at constant speed on a horizontalfloor by exerting a 43-N force on the handle, which makes an angle(theta) with the horizontal. The force of friction on the suitcaseis 27 N.
a. What angle does the handle make with the horizontal?
b. What is the normal force on the suitcase?
c. What is the coefficient of friction?
