The Batmobile, starting from rest, speeds up with an acceleration of magnitude 2.25 m/s2 through a distance of 225 m. It then applies the brake and slows down with an acceleration of magnitude 0.750 m/s2, until it finally stops after having traveled an additional distance of 675 m. Calculate the time that it takes to travel the entire 900 m from start to finish.

Answer #1

For first situataion acceleration is postive since speed up and second case acceleration is negative since slow down.

Here time takes to travel entire 900 m

Mechanic Physics: A car moves along an x axis through a distance of 920 m, starting at rest (at x = 0) and ending at rest (at x = 920 m). Through the first 1/4 of that distance, its acceleration is +4.80 m/s2. Through the next 3/4 of that distance, its acceleration is -1.60 m/s2. What are (a) its travel time through the 920 m and (b) its maximum speed? include units please and show work
