A 68.0 patient is suspended in a raised hospital bed (angle is 50 degrees). The wire is attached to a brace on the patient's neck and pulls parallel to the bed, and the coefficients of kinetic and static friction between the patient and the bed are 0.500 and 0.800, respectively. What is the maximum mass can be without the patient sliding up the bed?
