Question

11 6. The acceleration time graph of a particle moving along straight line is as shown in the figure. What is the velocity of the particle at t=8 sec, if initial velocity of particle is 3 m/s? ya(m/s) 4 11 4 0 gotis 8 t(s) (1) 4 m/s (2) 5 m/s (3) 1 m/s (4) 7 m/s ​

Answer 1

Answer:

Correct option is

B

4 m/s

Velocity= area of acceleration - time graph

⇒Velocity=

2

1

×2×4=4m/s

Answer 2

Answer:

7m/s

Explanation:

area of at graph is velocity

just - the negetive one

and final ans (area of trangle-area of square)+3(initial velocity given

so 7m/s
