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 per second the velocity at the at 8 seconds

plz explain ds

Answer 1

Answer:+15

Explanation: area of acceleration time graph gives velocity

Area of triangle = half * base * height

V = 1/2 * 6*10   -   1/2 * 2 *10

V = 30-10

V =20

But u = -5m/s

Therefore v=20-5 = 15m/s
