Rachel pulls her 177N suitcase at a constant speed by pulling on a handle that makes an angle (-) with the horizontal. Using frictional force on the suitcase as 27N and Rachels force on 43N on the handle to calculate the net force.

1. What angle does the handle make with the horizontal (since velocity is constant, the frictional force and horizontal component of the applied force are equal.

2. What is the Normal force exerted on the suitcase?
