As shown in the figure, the included angle θ = 3 between the inclined cableway of a tourist attraction and the horizontal line. When the manned carriage accelerates obliquely upward with acceleration A, people will not be satisfied with the carriage. Because the positive pressure of people on the bottom of the carriage is 1.25 times of its gravity, there are:

FN-mg=ma in the vertical direction

Solution: A =.25g

Let the acceleration in the horizontal direction be A water, then: A = Tan 3 = 33

So: A water.
