Characterize the motion of a car that's dripping oil The drawing below shows a straight horizontal road. It's about 650 meters and there are markings every 10.0[m with a label every 50.0[m]. Treat this as an x-axis with tx being east. A car that was dripping oil, one dro every second was traveling west on the road. The 40 dots along the road are the oil drops. Every tenth drop is marked with an arrow, just to make it easier to count them. A stopwatch was turned on as the car passed 650[m] the time of the drops that have arrows is labeled. To simplify the discussion, let's assume that we don't have to worry about the trajectory ofthe falling oil. The location of the dot is good enough to track the location of the car. We'll also assume that the car moved reasonably smoothly (for example it doesn't stop between drops since that would be very unusual for a car. 40.0[s] 30.0[s] 20.0[s] 10.0[s] o so 100 150 200 250 300 350 400 450 500 550 600 650 Xu East (+x)Explanation / Answer
Solving first 4 questions
2.1 fast means drops will be less so at t =20 it is fast
2.2 pressed back means accleration is most so when rate of change of drops is less. So at time at so at t=10 sec
2.3 forward means deaccleration is more so at t=30 sec
2.4distance=160 m
Speed=160/10=16 m/s
