A car and a truck are heading directly toward one another on a straight and narrow street, but they avoid a head-on collision by simultaneously applying their brakes at t = 0. The resulting velocity-versus-time graphs are shown in Figure 2-38. What is the separation between the car and the truck when they have come to rest, given that at t = 0 the car is at x = 15 m and the truck is at x = −35 m? (Note that this information determines which line in the graph corresponds to which vehicle )

- In a friendly game of chicken, Car A has a starting distance of 160m in front of Car B. Both cars start with the same speed of 100 km/h, and both cars accelerate at constant rates. Knowing that Car B accelerates at 4.25 m/s^2. And car A accelerates at 4.00 m/s^2 . Determine the position in meters, that they crash.arrow_forward-------*34 In Fig.2-27, a red car and a green car, identical except for the color, move toward each other in adjacent lanes and parallel to an x axis. At time t = 0, the red car is at x, = 0 and the green car is at x, = 220 m. If the red car has a constant velocity of 20 km/h, the cars pass each other at x = 44.5 m, and if it has a constant velocity of 40 km/h, they pass each other at x = 76.6 m. What are (a) the initial velocity and (b) the constant acceleration of the green car?-----I GOT THIS PART!!! THIS IS A REFERENCE.arrow_forwardMost important in an investigation of an airplane crash by the U.S. National Transportation Safety Board is the data stored on the airplane’s flight-data recorder, commonly called the “black box” in spite of its orange coloring and reflective tape.The recorder is engineered to withstand a crash with an average deceleration of magnitude 3400g during a time interval of 6.50 ms. In such a crash, if the recorder and airplane have zero speed at the end of that time interval, what is their speed at the beginning of the interval?arrow_forward

The left? (Answer in interval notation) The velocity of the object at t=1 is? Acceleration at t=1 is? The acceleration of the object when it’s velocity is zero is?

(Answer in interval notation)arrow_forwardTwo cars given by the king of France and queen of England (let them be named car F and car E) are straightly moving in a line. Their position functions are found to be respectively: z(t) = 14 m - (8m/s^2)t^2 and z(t) = - 50 m - (4m/s^2)t^2. At some point, these fancy and jaw-dropping cars from the said royals meet at about z' = 114 meters. From the given data, find the average velocity of car F from the time intervals t = 0 up to t'.

- On a one lane road, a person driving a car at v1 = 54 mi/h suddenly notices a truck 0.65 mi in front of him. That truck is moving in the same direction at v2 = 35 mi/h. In order to avoid a collision, the person has to reduce the speed of his car tov2 during time interval Δt. The smallest magnitude of acceleration required for the car to avoid a collision is a. During this problem, assume the direction of motion of the car is the positive direction. Refer to the figure.
