Final answer:
The position of the training helicopter at a specific time can be found by substituting the value of t into the given vector equation.
Step-by-step explanation:
The position of the training helicopter at time t is given by the vector r = (0.020t³)i - (2.2t)j - (0.060t²)k. To find the position of the helicopter at a specific time, substitute the value of t into the vector equation. For example, to find the position at t = 2.0 s, substitute t = 2.0 s into the equation to get r = (0.020(2.0)³)i - (2.2(2.0))j - (0.060(2.0)²)k. Calculate the resulting vector to find the position of the helicopter.
