Power using Derivative and Unit Vectors  Example (10:27)
Example: A 0.280 kg object has a position described by the function, position as a function of time equals 5.00 t^3  8.00 t^2  30.0 t meters. What is the net power being delivered to the object at 2.00 seconds? This is an AP Physics C: Mechanics topic.
