Braking distance is the distance a car travels from the time a person applies the brakes to when the car comes to a complete stop. the graph shows the relationship between the speed of a car and the distance the car travels before it stops.

based on the graph, describe the relationship between the car’s braking distance and kinetic energy. be sure to use evidence from the graph to support your response.

Aflask with vinegar in it has a mass of 160 grams. a balloon with baking soda in it has a mass of 40 grams. the balloon is attached to the flask to seal the opening and the vinegar and baking soda mixes. the balloon inflates to a large volume. what will the total mass of the balloon and flask be after the balloon inflates? explain. a) less than 200 grams because the solid baking soda disappears. b) 200 grams, because all the atoms remain in the balloon or flask. c) more than 200 grams because the size of the balloon is so much larger. d) less than 200 grams because gases such as the one in the balloon are lighter than solids and liquids.
