Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Part A: How many newtons does a 200 lb person weigh?
Step 2:: Convert pounds to kilograms
- Conversion factor: 1 lb $$\approx$$ 0.453592 kg
200 \text{ lb} \times 0.453592 \frac{\text{kg}}{\text{lb}} = 90.7184 \text{ kg}
Step 3:: Calculate weight using gravitational acceleration
W = 90.7184 \text{ kg} \times 9.8 \frac{\text{m}}{\text{s}^{2}} = 889.04 \text{ N}
- Weight formula: W = mg
Final Answer
Part B: Should a veterinarian be skeptical if someone said that her adult collie weighed 40 N? Step 1: Typical dog weight conversion - 40 N \div 9.8 \frac{\text{m}}{\text{s}^{2}} = 4.08 \text{ kg} - This is an extremely low weight for an adult collie (typically 14 - 25 kg) Part C: Should a nurse have questioned a medical chart showing that an average-looking patient had a mass of 200 kg? Step 1: Average human mass assessment - Typical adult mass range: 60 - 90 kg - 200 kg is significantly above normal human weight
