Please help with the Same Force 58 Cars and Barriers-Stopping Distance ified speeds. Also given are fe hown below are eight cars that are moving along horizontal roa nasses of the cars. All of the cars are the same size and shape, masses. All of these cars are going to be stoppe going to be stopped by the same constant force by the barrier but they are carrying loads with dif into identical bar riers. All of the cars are d by plowing ank these situations stop the cars with the sa Irom greatest to least on the basis of the stopping distance that will be needed to rce. That is, put first the car that requires the longest stopping distance and ut last the car that requires the shortest distance to stop the car with the same foir 10 m/s 20 m/s 30 m/s 10 m/s m 1000 kg m 1000 kg m = 1000 kg m 3000 kg 10 m/s 20 m/s 30 m/s 20 m/s 2000 kg m 2000 kg m 2000 kg m 3000 kg ongest 1 r, all the cars require the same distance ease carefully explain your reasoning Shortest w sure were you of your ranking? (circle one) sically Guessed Sure Very Sure n Maloney, C. Hieggelke Mechanics Solution As force is constant, dp/dt is constant which change in momentum with respect to change in time. A car with maximum stopping time will have maximum stopping distance. A car with maximum change in momentum will have maximum stopping distance. Therefore, Ranking will be G=H>F>C=D>B=E>A .
