Lesson 33 worksheet

  1. Time Height
    0 400 (0, 400)
    1 384 (1, 384)
    2 336 (2, 336)
    3 256 (3, 256)
    4 144 (4, 144)
    5 0 (5, 0)
  2. roller-coaster
  3. 400 ft., equation at 0 seconds (before the drop) results in 400 ft.
  4. at 5 seconds, the coaster is at the bottom.  At 5 seconds, the equation results in 0 ft.
  5.   V=Δh/Δt=400/5= 80 ft/sec
