If the speed were increased to 25 x  its speed, what would be the new force? ___________________ x original force.

The question seems to be related to the concept of force in physics. However, it's important to note that force is not directly proportional to speed. Force is related to the acceleration and mass of an object, not its speed, according to Newton's second law of motion (F=ma).

If you're referring to the drag force experienced by an object moving through a fluid, then it's a different case. The drag force is approximately proportional to the square of the speed. So if the speed were increased to 25 times its original speed, the new force would be (25^2) = 625 times the original force.

Please clarify the context of the question for a more accurate answer.
