Four race cars are traveling on a 2.5-mile tri-oval track. The four cars are traveling at constant speeds of 195 mph, 190 mph, 185 mph, and 180 mph respectively. Assume you are an observer standing at a point on the track for a period of 30 minutes and are recording the instantaneous speed of each vehicle as it crosses your point. Find the TSM, SMS, q, and k
Cars A and B approached each other on a straight road from points 457 meters apart. A has an initial speed of 76 kph and is decelerating at the rate of 0.44 m/s^2. B has an initial speed of 29 kph and is accelerating at the speed of 0.33 m/s^2. At what time (seconds) will the cars be 201 meters apart from each other? Round off to two decimal places.
Situation 1: Two automobiles A and B are approaching each other in adjacent highway lanes. At t = 0 seconds, A and B are 1 km apart, their speeds are VA = 110 kph and VB = 60 kph and they are at points P and Q respectively.

Present the solution, and inbix the answer.
NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Three seconds after automobile B passes through the intersection shown, automobile A passes through the same intersection. Given, the speed of automobile A is VA = 95.00 mi/h and automobile B is vg = 50.00 mi/h, respectively. Also, know that the speeds are constant for the automobiles during the encounter. N 70° S + VA vB Determine the distance between the two automobiles 2 s after A has passed through the intersection. The distance between the two automobiles 2 s after A has passed through the intersection is 356.5 ft.
A vehicle moving at a speed of 50 mph is slowing traffic on a two-lane highway. What passing sightdistance is necessary, in order for a passing maneuver to be carried out safely? Calculate the passingsight distance. In your calculations, assume that the following variables have the values given: Passing vehicle driver's perception/reaction time = 2.5 sec Passing vehicle's acceleration rate = 1.47 mph/sec Initial speed of passing vehicle = 50 mph Passing speed of passing vehicle = 60 mph Speed of slow vehicle = 50 mph Speed of opposing vehicle = 60 mph Length of passing vehicle = 22 ft Length of slow vehicle = 22 ft Clearance distance between passing and slow vehicles at lane change = 20 ft Clearance distance between passing and slow vehicles at lane re-entry = 20 ft Clearance distance between passing and opposing vehicles at lane re-entry = 250 ft
