A 50 kg passenger rides in an elevator cab that starts from rest on the ground floor of a building at t = 0 and rises to the top floor during a 10 s interval. The cab's acceleration as a function of the time is shown in Figure, where positive values of the acceleration mean that it is directed upward. What are the(a) Magnitude and(b) Direction (up or down) of the maximum force on the passenger from the floor, the(c) Magnitude and(d) Direction of the minimum force on the passenger from the floor, and the(e) Magnitude and(f) Direction of the maximum force on the floor from thepassenger?
