## Step 1: Calculate \( K_1 \) and \( K_2 \) (Initial and Final Kinetic Energy)
### Formula:
\[
K = \frac{1}{2} (m_H + m_k) v^2
\]
- \( m_H \) (hanging mass) = 6.92 g = .00692 kg
- \( m_k \) (cart mass) = from table (convert g to kg)
- \( v_1 \), \( v_2 \) from table (in m/s)
#### **Trial 1:**
- \( m_k = 6.92\, \text{g} = .00692\, \text{kg} \)
- \( v_1 = .127\, \text{m/s} \)
- \( v_2 = .584\, \text{m/s} \)
\[
K_1 = \frac{1}{2} (.00692 + .00692) (.127^2)
\]
\[
K_1 = .5 \times .01384 \times .016129 = .0001116\, \text{J}
\]
\[
K_2 = \frac{1}{2} (.00692 + .00692) (.584^2)
\]
\[
K_2 = .5 \times .01384 \times .341056 = .002362\, \text{J}
\]
**Repeat similarly for other trials.**
#### **Explanation:**
Here, you are calculating the initial and final kinetic energies for each trial using the masses and velocities provided, converting units where needed.
---
## Step 2: Calculate \( K_2-K_1 \), \( W_{net} \), and Uncertainty
### 1. **Kinetic Energy Change (\( K_2 - K_1 \)):**
Subtract \( K_1 \) from \( K_2 \) for each trial.
### 2. **Net Work Done (\( W_{net} \)):**
\[
W_{net} = m_H g d
\]
- \( m_H = .00692\, \text{kg} \)
- \( g = 9.8\, \text{m/s}^2 \)
- \( d = .95\, \text{m} \) (from 95 cm)
\[
W_{net} = .00692 \times 9.8 \times .95 = .0643\, \text{J}
\]
### 3. **Uncertainties:**
- For velocities and masses, use the uncertainties given.
- For combined uncertainties, use propagation rules (e.g., for multiplication: \(\frac{\Delta Q}{Q} = \sqrt{(\frac{\Delta a}{a})^2 + (\frac{\Delta b}{b})^2 + ...}\))
#### **Explanation:**
You find the change in kinetic energy for each trial and calculate the net work, then account for uncertainties using propagation rules.

## Final Answer: Results Table Format
| Trial | \( K_1 \) (J) | \( K_2 \) (J) | \( K_2-K_1 \) (J) | \( W_{net} \) (J) | N (Uncertainty) |
|-------|---------------|---------------|-------------------|-------------------|-----------------|
| 1 | .0001 ± X | .0024 ± X | .0023 ± X | .0643 ± Y | ... |
| 2 | ... | ... | ... | .0643 ± Y | ... |
| 3 | ... | ... | ... | .0643 ± Y | ... |
- \( X \): Propagated uncertainty from mass and velocity
- \( Y \): Uncertainty from \( m_H \), \( g \), and \( d \)
