Question

I need help with question D).

A woman at an airport is towing her 20kg suitcase at constant speed by pulling on the strap at an angle of 90 above the horizontal with a force of 35N. There is a 20N resistive force acting opposite the direction of motion of the suitcase. a) Draw a free body diagram of the suitcase b) What is the angle 8 ? Ex= 35cos-20 = 20/35 = 55.2 degrees c) What is the magnitude of the Normal force N that the ground exerts on the suitcase? Ey = N + 35sin(55.2) – 196 = 0 Ey = 196 - 35sin(55.2) = 167 N %3D d) the tension in the strap and the angle were the same? How would the problem change if the resistive force were only 18N, but
