A rocket-powered sled moves along a track, eventually reaching a top speed of 192 m/s to the west. It then begins to slow down, reaching a complete stop after slowing down for 4.71 s. What was the sled s average acceleration and velocity during the slowdown phase? 40.8 m/s^2 west, not enough information 96 m/s^2 east, 96 m/s east 40.8 m/s^2 east, not enough information 0 m/s^2 0, 96 m/s west

The citizen leaves a city at 3:00 p.m. It travels at 36.0 m / s when the engine of its car stops. During the next twelve seconds, the car slows down and its average acceleration is a1. Over the next six seconds, the car slows down even further, and its average acceleration is a2. The speed of the car is 28.0 m / s. The ratio of the average acceleration values ​​is a1 / a2 = 1.50. (a) Find the speed of the car at the end of the initial twelve second interval. (b) Calculate the total distance traveled by the car before stopping.

A car traveling with an initial velocity of 26.75 m/s to the east, sees a wall 68.12 meters to its east. It applies the break and slows down with an acceleration of 3.22 m/s² to the west. How fast is the car in m/s when it hits the wall?

A blue car travels down a straight road at a constant speed of 19.9 m/s. As they pass a red car, initially stopped on the side of the road, the red car speeds up at a rate of 1.80 m/s?. How much distance (in m) does the red car travel before it overtakes the blue car?
