This may be very simple... but here is the question.
This is the question..
A woman at an airport is towing her 20.0 kg suitcase at constant speed by pulling on a strap at an angle of (theta) above the horizontal. She pulls on the strap with a 35.0 N force, and the friction force on the suitcase is 20.0 N. What angle does the strap make with the horizontal? What normal force does the ground exert on the suitcase?
I got the first part. The vertical component of the angle is 26 N. So if the suitcase is 20 kg and she is pulling vertically 26 N, shouldn't she be lifting the suitcase? how do i figure out the normal force which the ground exerts?
