Question:

The parachute on a race car of weight {eq}8,850 \ N {/eq} opens at the end of a quarter-mile run when the car is traveling at {eq}31 \ m / s {/eq}. What total retarding force must be supplied by the parachute to stop the car in a distance of {eq}1,070 \ m {/eq}?

Force:

A force is a quantity that is formally defined to give motion to a stationary object. A force can also change the motion of an object in a way that the object either speeds up or slows down. Forces are vector quantities, which means that forces have both a magnitude and a direction.
