- 187.237 km/hr fast is θ changing 12 min after the plane passes over the radar station
<u>Explanation:</u>
Let the distance x and angle θ be defined as in the figure below. Then
Now, differentiate with respect to t, we get
Now, calculate the travel distance from radar station to plane after 12min
Distance,
Substituting ‘x’ value, we get
Find the rate of change of theta after 12 min,
We know, the formula for,
So, then,
When express the value in km/he, we get, the change in theta as
