To solve this problem, we need to:

1. Determine the angular acceleration of the flywheel caused by the given force.
2. Calculate the rotational kinetic energy stored in the flywheel after the specified time.

I'll outline the process to solve these questions step by step:

Step 1: Angular Acceleration

Angular acceleration $\alpha$ can be determined using the relationship: $\alpha = \frac{\tau}{I}$ where:

• $\tau = r \cdot F$ is the torque (force times radius),
• $I = \frac{1}{2} m r^2$ is the moment of inertia of a solid flywheel,
• $r$ is the radius in meters,
• $F$ is the applied force in newtons,
• $m$ is the mass in kilograms.

Step 2: Rotational Kinetic Energy

Rotational kinetic energy $(KE_{\text{rot}})$ is given by: $KE_{\text{rot}} = \frac{1}{2} I \omega^2$ where:

• $\omega = \alpha t$ is the angular velocity after $t$ seconds,
• $t$ is the given time.

Please provide the missing numerical values for:

1. Mass of the flywheel ($m$),
2. Radius of the flywheel ($r$) in centimeters,
3. Force ($F$) applied,
4. Time duration ($t$).

With this information, I can calculate the answers for both questions!
