### Jet Pilot Vertical Loop Problem

A jet pilot takes his aircraft in a vertical loop, as shown in the figure.

**Figure Details:**
- The diagram illustrates a circular vertical loop with an aircraft positioned at two points: the top and the bottom of the loop, indicating the path taken by the jet.

---

### Problem Statement

#### Part A

**Objective:**
Determine the minimum radius of the circle needed so that the centripetal acceleration at the lowest point does not exceed 6.5 g's.

- **Given:**
  - Speed of the jet: 940 km/h

**Instructions:**
Express your answer with two significant figures including appropriate units.

- **Input Field:**
  - \( r = \) [Text box for input] km

**Feedback Mechanism:**
- Submission results in an "Incorrect; Try Again" prompt with a note of remaining attempts (4 remaining).

---

#### Part B

**Objective:**
Calculate the 76-kg pilot's effective weight (force exerted by the seat) at the bottom and top of the circle, assuming constant speed.

- **Given:**
  - Pilot's mass: 76 kg

**Instructions:**
Express answers using two significant figures separated by a comma.

- **Input Field:**
  - \( F_{\text{bottom}}, F_{\text{top}} = \) [Text box for input] N

**Buttons:**
- "Submit" button
- "Request Answer" option
