Aparticle is moving along a straight line such that when it is at the origin it has a velocity of 8 m/s.

               a = 4 * t^2 – 2
At t = 0, a = -2 m/s^2
At t = 2, a = 4 * 2^2 – 2 = +14 m/s^2
At t = 4.3, a = 4 * 4.3^2 – 2 = 71.96 m/s^2

The acceleration is constantly increasing. The graph of acceleration vs time a parabola. The area under this graph is the velocity. The area under the velocity graph is the displacement. We have some integrating to do.

Velocity is the integral of acceleration
Integral of 4t^2 – 2 = 4/3t^3 – 2t + c

Position is the integral of velocity
Integral of 4/3t^3 – 2t + c = ⅓ * t^4 – t^2 + c * t + d

Position = ⅓ * t^4 – t^2 + c * t + d
Initial position = 1
At t = 0, position = 1
1 = ⅓ * 0^4 – 0^2 + c * 0 + d
1 = d
Position = ⅓ * t^4 – t^2 + c * t + 1 

At t = 2, position = 20
20 = ⅓ * 2^4 – 2^2 + c * 2 + 1
20 = 5⅓ – 4 + c * 2 + 1
20 = 2⅓ + c * 2
17⅔ = c * 2
8.8333 = c

Position = ⅓ * t^4 – t^2 + 8.833 * t + 1
Position = ⅓ * 4.3^4 – 4.3^2 + 8.833 * 4.3 + 1
The answer is approximately 134.45 m 

Your answer is c. explanation: plasma  is the fourth state of matter, derived from the gaseous state of matter.  plasma  can contain free  electrons  and/or  ions. while  plasma is never neutral, it can either be positively or negatively charged.  gases, however, are electrically neutral.
