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?

Andrew Cobb · Answer 1

The equation that would allow us to calculate for the force is expressed as,

F = 0.5mv²

If we are to evaluate the use of 5 miles per hour then, the equation would be,

F = 0.5m (5 m/s) ² = 12.5m

For the second given speed,

F = 0.5m₁ (10 m/s) ² = 50m

The fraction between the forces is equal 4.
