Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

### Educational Content: Automotive Starter Gear Analysis

For a short time, gear \( A \) of the automobile starter rotates with an angular acceleration given by:

\[
\alpha_A = (45t^2 + 40) \, \text{rad/s}^2
\]

where \( t \) is in seconds. (Refer to **Figure 1** for a visual representation.)

#### Figure Description:
The figure illustrates a mechanical configuration of an automobile starter. It depicts gears labeled \( A \) and \( B \). These gears are part of a system that transfers rotational motion to start the vehicle.

### Problem-Solving Parts:

#### Part A:
You need to determine the angular velocity of gear \( B \) when \( t = 2 \, \text{s} \), assuming the system starts from rest. The radii of gears \( A \) and \( B \) are 10 mm and 25 mm, respectively.

- **Task:** Express the angular velocity \( \omega_B \) in terms of three significant figures and include the appropriate units.

#### Input:
\[
\omega_B = \text{Value} \,\, \text{Units}
\]

Submit your solution using the provided input box.

#### Part B:
Determine the angular displacement of gear \( B \) when \( t = 2 \, \text{s} \), with the system starting from rest.

- **Task:** Express the angular displacement \( \theta_B \) with three significant figures and include the appropriate units.

#### Input:
\[
\theta_B = \text{Value} \,\, \text{Units}
\]

Enter your response and submit for evaluation.

### Additional Features:
For both Parts A and B, utilize the submission buttons to submit your calculations. You may request feedback or hints by selecting the "Request Answer" option.
