An automotive research facility is testing a new design on bumpers to determine the force at which it will break. The formula for Force is F = 1 2 m v 2 Where m is the mass (weight) and v is the velocity (speed) What is the effect on the force if the velocity changes from 5 miles per hour to 10 miles per hour?
