$\tt{\huge{\blue{Explanation:}}}$

The kinetic energy of a moving object is given by

$\boxed{KE = \frac{1}{2}mv^{2}}$

where:

KE = kinetic energy

m = mass

v = speed

$\tt{\huge{\red{Solution:}}}$

Solving for v

$KE = \dfrac{1}{2}mv^{2}$

$2KE = mv^{2}$

$v^{2} = \dfrac{2KE}{m}$

$v = \sqrt{\dfrac{2KE}{m}}$

$v = \sqrt{\dfrac{2(\text{12,525 J})}{\text{42 kg}}}$

$\boxed{v = \text{24.42 m/s}}$

Therefore, Missy's speed is 24.42 m/s.
