The acceleration of a train between two stations is shown in the figure. The maximum speed of the train is

Options

  1. A60 ~m / s
  2. B30 ~m / s
  3. C120 ~m / s
  4. D90 ~m / s

Correct answer

B. 30 ~m / s

Step-by-step solution

aligned & v_ = Maximum positive area of a-t graph & = area between 0 and 8 ~s & Area of triangle + Area of rectangle = 1 2 4 5+4 5 & =30 ~m / s aligned
