4. The Trendelenburg Position. In emergencies with major blood loss, the doctor will order the patient placed in the Trendelenburg position, in which the foot of the bed is raised to get maximum blood flow to the brain. If the coefficient of static friction between the typical patient and the bedsheets is 1.20, what is the maximum angle at which the bed can be tilted with respect to the floor before the patient begins to slide? Consider that the mass = 1.5 kg 5. Consider the shown in the figure below. Block A weighs 45.0 N and block B weighs 25.0 N. Once block B is set into downward motion, it descends at a constant speed. (a) Calculate the coefficient of kinetic friction between block A and the tabletop. (b) A cat, also of weight 45.0 N, falls asleep on top of block A. If block B is now set into downward motion, what is its acceleration (magnitude and direction)? B 6. In the figure below. m₁ = 20.0kg and a = 53.10. The coefficient of kinetic friction between the block and the incline is = 0.40. What must be the mass of m₂ of the hanging block if it is to descend 12.0 m in the first 3.00 s? a
