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)
10-
8
-t(s)
+
2 4 4 6
-10​

Answer 1

Explanation:

The zeros of the polynomial

2

- 3x – 4 are

(a) 4, -1 (b) 4, 1 (c) -4, 1 (d) -4, -1

Answer 2

Answer:

area of a-t graph gives???

- velocity..no!!!!!!!....CHANGE IN VELOCITY....remember acceleration is the rate by which velocity changes

• now calculate the area ...and don't forget to subtract the negative area...

hope it helps...

Good luck
