6 (s)(8c2p39) As two trains move along a track, their conductors suddenly notice that they are headed toward each other. The figure gives their velocities v as a function of time t as the conductors slow the trains.The figure's vertical scaling is set by v. = 22 m/s.The slowing process begins when the trains are 183.00 m apart. What is their separation when both trains have stopped?v (m/s)

The vertical scaling is given as vs = 22 m/s for the 4 positive vertical blocks so the scale per…

A red Mazda Miata (type of car) accelerates from rest at a rate of a₁ in the positive x direction for a total of 20.0 seconds. The Mazda then holds their speed and direction constant for a 20.0 additional seconds. Finally, while continuing in the positive x direction, the Mazda slows down at a rate of a2 until the car stops moving.

As two trains move along a track, their conductors suddenly notice that they are headed toward each other. The below figure gives their velocities v as functions of time t as the conductors slow the trains. The figure's vertical scaling is set by v = 40.0 m/s.

Car A was traveling east at high speed when it collided at point O with car B , which was traveling north at 45 mi/h. Car C , which was traveling west at 60 mi/h, was 32 ft east and 10 ft north of point O at the time of the collision. Because the pavement was wet, the driver of car C could not prevent his car from sliding into the other two cars, and the three cars, stuck together, kept sliding until they hit the utility pole p. Knowing that the weights of cars A, B, and C are, respectively, 3000 lb, 2600 lb, and 2400 lb, and neglecting the forces exerted on the cars by the wet pavement, solve the problems indicated.Knowing that the coordinates of the utility pole are xp= 46 ft and yp = 59 ft, determine (a) the time elapsed from the first collision to the stop at P,(b) the speed of car A.
