Answer:

Explanation:

The formula for KE is

[tex]KE=\frac{1}{2}mv^2[/tex] which makes solving our problem for velocity super easy. We will rewrite the formula in terms of v to get:

[tex]v=\sqrt{\frac{2KE}{m} }[/tex] and filling in:

[tex]v=\sqrt{\frac{2(50)}{25} }[/tex] so

v = 2 m/s to the correct number of sig fig's
