The formula E=12mv2 is used to find kinetic energy of an object with mass, m, and velocity, v. Solve for v.

v=±m2E
v=±m2E‾‾‾√
v=±2Em‾‾‾√
v=±2Em

The lengths of nails produced in a factory are normally distributed with a mean of 4.91 centimeters and a standard deviation of 0.05 centimeters. find the two lengths that separate the top 4% and the bottom 4%. these lengths could serve as limits used to identify which nails should be rejected. round your answer to the nearest hundredth, if necessary.
