If a 1,279 car is moving at 26.82 m/s when it hits a truck, resulting in a 20,000 N force that slows the car down to 10 m/s, for how long did the car experience the force

When calculating percentage we need two numbers. one number represents total amount of certain thing and another number represents partial number of that thing. then we divide those two numbers.in this problem total amount represents total number of weeds growing on some surface. partial number represents chicory.percentage = partial / total * 100%percentage = 29 / 98 * 100%percentage = 29.6%our calculation is closest to answer b) so this is our correct answer.
