1. Henry is standing on a scale inside of an elevator. The scale measures Henry's apparent weight as the elevator accelerates upward and downward. The elevator, initially at rest, begins to move at t=0s. Figure 1 shows the reading on the scale during the next 12s. Assume that the elevator is moving with constant velocity from t=2s until t=10s. (a) From t = Os until t = 2s, in which direction is the elevator accelerating? (i.e., upward or downward?) (b) From t = Os until t = 2s, in which direction is the elevator moving? (i.e., upward or downward?) (c) What is Henry's mass? (d) How far does Henry travel during the interval from t=0s until t=12s? w (N) 900 750 600 0+ 0 2 4 6 8 10 12 FIGURE 1 -t (s) 1.
