A car started from rest and accelerates with 2.4 m/s2 for 8.8 seconds. It then travels with the constant velocity it has achieved for another 9.9 seconds. Then it finally slows to a stop with a constant acceleration of 3.4 m/s2. How far does the car travel after starting from rest?

367.616 m

Explanation:

The distance it travels for the 1st segment is

The constant velocity that it achieves in the 2nd segment is

The distance it travels in the 2nd segment is

The distance it travels in the last segment when coming from 21.12 m/s to rest (0 m/s) at the rate of -3.4 m/s2 is

The total distance is has traveled from rest is

92.928 + 209.088 + 65.6 = 367.616 m

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
