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 

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
