Transcribed Image Text:**Scenario Description:**
A 80 kg astronaut is training in a human centrifuge to prepare for a launch. The astronaut uses the centrifuge to practice having a 6.01g force (6.01 times his own weight) on his back.
**Checklist and Questions:**
- **Number of forces in plane:** 3
- **Centripetal force:** Normal force
- **Are all forces balanced?** No
**Calculations Required:**
1. **How much force is acting on the astronaut's back?**
- (Dropdown for unit selection)
2. **What is the centripetal net force on the astronaut?**
- (Input box for numerical answer)
- (Dropdown for unit selection)
3. **What is the astronaut's centripetal acceleration?**
- (Input box for numerical answer)
- (Dropdown for unit selection)
4. **What is the astronaut's linear speed?**
- (Input box for numerical answer)
- (Dropdown for unit selection)
5. **What is the astronaut's angular speed?**
- (Input box for numerical answer)
- Unit: rad/s, rpm
**Diagram Explanation:**
The diagram depicts a human centrifuge setup with a 12-meter radius. It illustrates an astronaut positioned in a compartment at the end of the centrifuge arm, which rotates around a central axis. Arrows indicate the rotational direction, emphasizing the centrifugal experience during the training. A zoomed-in view shows the astronaut inside the compartment.
