Question 1: What is the centripetal force of a 30 kg child at 1.0 m from the center? using gresa method

The **GRESA method** is an organized approach to solving physics problems, where each letter represents a step in the solution process:

- **G**: Given
- **R**: Required
- **E**: Equation
- **S**: Solution
- **A**: Answer

Let's solve the problem.

### Question
**What is the centripetal force of a 30 kg child at 1.0 m from the center?**

### Solution (using GRESA method)

#### 1. **G (Given)**
   - Mass of the child, \( m = 30 \, \text{kg} \)
   - Radius of the circular path, \( r = 1.0 \, \text{m} \)
   - Assuming the velocity is not given, we cannot directly calculate the centripetal force without velocity or angular velocity.

#### 2. **R (Required)**
   - Centripetal force \( F_c \).

#### 3. **E (Equation)**
   The formula for centripetal force is:
   \[
   F_c = \frac{m v^2}{r}
   \]
   where:
   - \( F_c \) is the centripetal force,
   - \( m \) is the mass,
   - \( v \) is the linear velocity,
   - \( r \) is the radius of the circular path.

#### 4. **S (Solution)**
   To proceed, we need either the **velocity \( v \)** of the child or the **angular velocity \( \omega \)** of the child (where \( F_c = m \omega^2 r \)).

Without these values, we cannot compute the centripetal force.

### Tip
Remember that centripetal force is always directed towards the center of the circular path, and it keeps an object in motion along a curved path.
