Question

mission kc5: oil drop representations based on the oil drop pattern for car a and car b, which of the following statements are true? select all that apply. a. both cars have a constant velocity. b. both cars have an accelerated motion. c. car a is accelerating; car b is not. d. car b is accelerating; car a is not. e. car a has a greater acceleration than car b. f. car b has a greater acceleration than car a. g. none of these

Explanation:

Step1: Analyze Car A's pattern

The oil - drop pattern of Car A has equal spacing between consecutive drops over time. This indicates a constant velocity as the distance traveled in equal time intervals is the same.

Step2: Analyze Car B's pattern

The oil - drop pattern of Car B has increasing spacing between consecutive drops over time. This implies that the car is covering more distance in each successive equal time interval, which means it is accelerating.

Step3: Evaluate the statements

• Statement a: Car A has a constant velocity but Car B is accelerating, so this is false.
• Statement b: Only Car B is accelerating, so this is false.
• Statement c: Car A has a constant velocity and Car B is accelerating, so this is true.
• Statement d: This is false as Car A is not accelerating and Car B is.
• Statement e: Since Car A is not accelerating and Car B is, this is false.
• Statement f: Since Car A is not accelerating and Car B is, this is true.
• Statement g: Since c and f are true, this is false.

Answer:

c. Car A is accelerating; Car B is not.
f. Car B has a greater acceleration than Car A.
