Question

mission kcs: 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 constant velocity

If a car has a constant velocity, the oil - drop pattern will have equal spacing between consecutive drops. Neither Car A nor Car B has equal - spaced drops, so they do not have a constant velocity.

Step2: Analyze acceleration

Accelerated motion is indicated by an increasing or decreasing spacing between the oil drops. The spacing between the oil drops of both Car A and Car B is increasing, which means both cars are accelerating.

Step3: Compare accelerations

The rate of increase in the spacing of Car B's oil drops is greater than that of Car A's. So Car B has a greater acceleration than Car A.

Answer:

b. Both cars have an accelerated motion.
f. Car B has a greater acceleration than Car A.
