Question

Velocity time (v - t) graph r a moving object is shown in the figure. Total displacement of the object during the time interval when there is non-zero acceleration and retardation is - (A) 60 m (B) 50 m (C) 30 m (D) 40 m

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 =(1/2) × 20 × 3+20 × 1=30+20=50 m

Q. Velocity time $(v - t)$ graph $r$ a moving object is shown in the figure. Total displacement of the object during the time interval when there is non-zero acceleration and retardation is -

60 m

50 m

30 m

40 m

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 $40 s$
$= \frac{1}{2} \times 20 \times 3 + 20 \times 1 = 30 + 20 = 50 m$
