Aracecar is equipped with a computer that records the reading on its speedometer every second during a race. if you graph this data, what will be the best choice for the dependent variable?

Since the device is a speedometer, the data it read is the speed of the racecar. Data recording involving time usually uses time as the independent variable. It was also said in the problem that it records the speed every second which shows that the time interval is constant. This means that only other data, the car's speed, is the dependent variable.

When a passenger is in the car on a turn. they will most likely slide twords the door. this is because gravity is giving a pushing force twords the way it is turning. this force also acts upon the passenger, causing them to move.
