A car in stop-and-go traffic starts at rest, moves forward 25min 8.0s, then comes to rest againWhat is the constant speedVthat characterizes the middle portion of its motion?Express your answer using two significant figures.

When last we left our friend Wile E. Coyote (SuperGenius), was peeling himself off a canyon wall and none the worse for wear. This time, he has obtained an Acme^ TM rocket-powered dragster with the AcmeTM Premium Parachute Braking System (patent pending)Starting from restthe dragster accelerates at a constant rate of 36.4 m/s ^ 2 for 14 seconds. At this point, the coyote realizes that he has passed the Road Runner and so he instantly cuts off the engine and deploys his braking system - which doesn't work. He therefore travels an additional distance of 1800 m at constant velocity until again becoming one with a canyon wall. Determine: (a) The total time for Wile E. Coyote's motion described above; on (b) The total distance covered by Wile E. Coyote's motion described above ; (c) The average velocity for Wile E. Coyote's motion described above.

A car starts from rest, then accelerates at a constant rate over a distance of 57 m. It then immediately decelerates at a constant rate over a distance of 113 m. The entire trip lasts a total duration of 27.5 s. What were the magnitudes of the car s accelerations for the speedup and slowdown stages respectively?   The car comes to a complete stop at the end of the braking phase.     a. 4.11 m/s^2, then 2.07 m/s^2   b. 1.34 m/s^2, then 0.68 m/s^2   c. 2.07 m/s^2, then 4.11 m/s^2   d. 0.45 m/s^2, then 0.45 m/s^2

The brakes are applied to a moving car, causing it to uniformly slow down. While slowing, it moves a distance of 40.0 m in 7.40 s to a final velocity of 1.50 m/s, at which point the brakes are released. What was its initial speed (in m/s), just before the brakes were applied? What was its acceleration (in m/s2) while the brakes were applied? (Assume the initial direction of motion is the positive direction. Indicate the direction with the sign of your answer.)
