A train starts from rest and accelerates uniformly, until it has traveled 3 km and acquired a velocity of 20 m/s The train then moves at a constant velocity of 20 for 400 s. The train then slows down uniformly at 0.065 m/s2 until it is brought to a halt. Calculate the total ...

**physics! description explanations **

The graph at the right is a positive vs. Time graph for the motion of an object moving along a horizontal (x) axis For each of the 8 1-second time intervals, describe the displacement, instantaneous velocity (+/- and whether the velocity is increasing or decreasing) and the ...

**calculus**

The graph of f'(x) is shown for 0=< x =<10. The areas of the regions between the graph of f' and the x-axis are 20, 6, and 4, respectively. I'm going to describe the graph of f' since I can't post pictures. The first section of the graph goes up (like the sin function) ...
