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?

The force increases by 4 units when velocity changes from 5 miles per hour to 10 miles per hour.

Explanation: The force is given by the formula:

Force when v = 5 miles per hour

Force when v = 10 miles per hour

Taking ratio of and

Hence, the force is increased by 4 units when velocity changes from 5 miles per hour to 10 miles per hour.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
