I don’t have the rest of the problem — I only see “What was the original height of the helicopter?” Please paste the full problem or give the known numbers (final height, time, speeds or acceleration, etc.).
Meanwhile, here are the formulas you’ll likely need depending on the situation:
- Constant vertical speed (descent or climb at constant v): h0 = h(t) − v·t (if v is positive downward) or h0 = h(t) + v·t (if v is given positive upward). Example: if it descended at 3 m/s for 8 s and is now 20 m above ground, h0 = 20 + 3·8 = 44 m.
- Constant acceleration (vertical motion with initial speed v0 and acceleration a): h(t) = h0 + v0·t + ½ a t^2, so h0 = h(t) − v0·t − ½ a t^2.
- Percent change: if final height is p% of original, h0 = h_final / (p/100).
Send the specific numbers and I’ll compute the original height.
