Consider the following velocity and time graph: Which one of the following is the value of average acceleration from 8 s to 12 s ?

Options

  1. A8 ~m / s ^2
  2. B12 ~m / s ^2
  3. C2 ~m / s ^2
  4. D-1 ~m / s ^2

Correct answer

D. -1 ~m / s ^2

Step-by-step solution

Acceleration is defined as rate of change of velocity with time, hence aligned & a =4-8 / 4 & =-1 ~m / s ^2 aligned
