Compute all parts of given question:
Question: A student pulls her 22-kg suitcase through the airport at a constant velocity. The pull straps makes an angle of 50 degrees above the horizontal line. If the frictional force between suitcase and floor is 75N,
Part A: What force is the student exerting?
Part B: What is the coefficient of friction?
