Question
“1 2 3” are all part of the same problem that all refer to the info at the top.
**Problem 2:**

The moment the batmobile passes through the point \((-1, \sqrt{3})\), the angle \(\theta\) is changing at a rate given by

\[
\frac{d\theta}{dt} = 3 \, \text{rad/hr}.
\]

Find the rate at which the batmobile’s horizontal velocity, \(\frac{dx}{dt}\), is changing at this time.

**Problem 3:**

Find the rate at which the distance between the batmobile and the origin \((0, 0)\) is changing the moment the batmobile passes through the point \((-2, 0)\).

**Title: Calculating Rates of Change in Circular Motion**

Batman is at it again, driving his vehicle frantically around Wayne Manor (luckily avoiding Alfred’s freshly planted patch of dwarf cypress and gardenia). This time, the Batmobile moves counterclockwise along a circular path given by the equation:

\[ x^2 + y^2 = 4. \]

Let \(\theta\) denote the angle formed between the Batmobile and the positive x-axis at time \(t\).

**1. Problem 1**

At the moment the Batmobile passes through the point \((\sqrt{2}, \sqrt{2})\), its vertical velocity (in miles per hour) is given by:

\[ \frac{dy}{dt} = 30 \text{ mi/hr}. \]

Find the rate (in radians per hour) at which the angle \(\theta\) is moving at this time.

**2. Problem 2**

At the moment the Batmobile passes through the point \((-1, \sqrt{3})\), the angle \(\theta\) is changing at a rate given by:

\[ \frac{d\theta}{dt} = 3 \text{ rad/hr}. \]

Find the rate at which the Batmobile’s horizontal velocity, \(\frac{dx}{dt}\), is changing at this time.
