A truck weighing 70,000 lbs. is moving at 5 fps. on level ground. The brakes are applied and decelerates over the course of 1 foot. How much lateral force will be be exerting for that 1 second. Need a formula.
Thanks Signman

Signman, the formulas should be in your physics textbook, in the section dealing with uniform or constant acceleration. Try looking there.

You'll need to show an attempt at solving the problem before receiving help.

Sourab, please refrain from giving out the equations before people try solving the problem themselves.
