Question

The acceleration-time graph for a particle moving
along x-axis is shown in figure. If the initial velocity
of particle is -5 m/s, the velocity at t = 8 s is
a (m/s)
(1) +15 m/s
(3) -15 m/s
(2) +20 m/s
(4) -20 m/s
​

Answer 1

Answer:

15m/s is the answer

area of a-t graph

1/2x10x6-1/2x10x2=20

acceleration = change in velocity

20-5 = 15m/s

Answer 2

Answer:

+20m/s

Explanation:

+20m/s

I think so it will be the answer
