The velocity-time graph of a body moving in a straight line is shown in fig. Find the displacement and distance travelled by the body in 10 seconds.

Options

  1. A50 ~m , 90 ~m
  2. B5 ~m , 9 ~m
  3. C9 ~m , 5 ~m
  4. D90 ~m , 50 ~m

Correct answer

A. 50 ~m , 90 ~m

Step-by-step solution

Total distance covered in 10 ~s = Area 1+ Area 2+ Area 3 1 2 6 20+ 1 2 2 20+ 1 2 2 10=90 ~m Total displacement in 10 ~s = Area 1- Area 2 + Area 3 1 2 6 20- 1 2 2 20+ 1 2 2 10=50 ~m
