A body with a mass of 8.06 kg moves along the \( x \)-axis, influenced by a conservative force \( F(x) \).

\[
\vec{F}(x) = \Lambda x^3 \hat{x} \quad \text{where} \quad \Lambda = -4 \frac{N}{m^3}
\]

When the body is at position \( x_i = 2.05 \, \text{m} \), it is moving with a speed of \( v_i = 6.01 \, \text{m/s} \). What is the body's speed when it is at position \( x_f = -2.57 \, \text{m}? \)

\[
\text{speed:} \quad \underline{\hspace{3cm}} \quad \text{m/s}
