Question 3.34) A helicopter gets into difficulty at time t= 0. Its altitude (in meters) is given by p(t)=300²-²-4t+200 from time t=0 until t = 50 seconds when the pilot feels that everything is back to normal. A) At what speed is the helicopter falling when the frightened pilot first gets into difficulty? B) What is the (vertical component of the) acceleration of the helicopter at time t = 10, still frightening the pilot? C) At what time is the vertical velocity zero? D) What is the minimum height reached by the helicopter during those difficult times? Hint: What would then be the vertical speed at such a moment?
