Question

Rachel Pulls her 18 KG suitcase at at a constant speed by pulling on a handle that makes and angle (theta) with the Horizontal the frictional force of the suitcase is 27 N and Rachel exerts a 43 N force on the handle
What angle does the handle make with the horizontal?

Henry · Answer

The movement of the suitcase is afected only by the hor. component of the force exerted by Rachel: X = hor. = 43*cosA = 27, cosA = 27/43 = 0.6279, A = 51.1 Deg.
