**Problem (b):** Find the mechanical energy lost due to friction if \( v_f = 16.0 \, \text{m/s} < 20.7 \, \text{m/s} \).Write Equation 5.12, substituting expressions for the kinetic and potential energies.\[ W_{nc} = (KE_f - KE_i) + (PE_f - PE_i) \]\[ = \frac{1}{2} mv_f^2 - \frac{1}{2} mv_i^2 + mgy_f - mgy_i \]Substitute \( m = 58.3 \, \text{kg}, \, v_f = 16.0 \, \text{m/s}, \, \text{and} \, v_i = 0 \), and solve for \( W_{nc} \).\[ W_{nc} = \left[\frac{1}{2} \times 58.3 \, \text{kg} \times (16.0 \, \text{m/s})^2 + 0\right] \]\[ + \left[0 - 58.3 \, \text{kg} \times (9.80 \, \text{m/s}^2) \times 21.9 \, \text{m} \right] \]\[ W_{nc} = \boxed{-6256} \, \text{J} \]**Note:** Your response differs from the correct answer by more than 10%.
