Question

12 122. The velocity-time graph of an object is shown. The distance during the interval 0 to t, is :- С. 0. t₂ (1) Area A + Area B + Area C + Area D + Area E (2) Area A + Area C - Area B - Area D (3) Area A + Area B + Area C + Area D (4) Area A + Area C + Area E - Area B + Area D​

Answer 1

Answer:

Between time interval 20 s te 40 s, there is non-zero acceleration and retardation. Hence, distance travelled during this interval

= Area between time interval 20 s to 40 s
