A helicopter traveling east at 100 m/s and an elevation of 1500 meters kicks a package northward at 5 m/s. The helicopter then decelerates at 3 m/s^2. How fast is the distance between the copter and package changing at t=4 seconds?
The Attempt at a Solution
I took the derivative of the distance formula and plugged in the values from the word problem. I would just like to verify my answer, which was 34.19 m/s.
