An inquisitive physics student, wishing to combine pleasurewith scientific inquiry, rides on a rollercoaster sitting on abathroom scale. (Do not try this yourself on a rollercoaster thatforbids loose heavy packages.) The bottom of the seat in therollercoaster car is in a plane parallel to the track. The seat hasa perpendicular back and a seat belt that fits around the student'schest in a plane parallel to the bottom of the seat. The studentlifts his feet from the floor, so that the scale reads his weight,190 lb, when the car is horizontal. Atone point during the ride, the car zooms with negligible frictiondown a straight slope inclined at 30.0° below the horizontal. What does the scale read at that point?
