A2kg particle moving along the x-axis experiences the net force shown at right. the particle’s velocity is 3.0m/s at x = 0m. a) at what position is the particle moving the fastest? b) what is the particle’s velocity at x=8m? show your work

A. Fastest speed at x >= 8m. The fastest ACCELERATION is at x=6m
b. Speed is 5 m/s

Initial velocity is 3.0 m/s
Initial energy is 9 Joules.
Area under curve is 16 Joules
Energy at 8m is 9+16 = 25 joules
And for a particle that masses 2 kg to have 25 joules,
it needs a velocity of 5 m/s

Remember, area of triangle is 1/2 base * height. And the curve above is a triangle with base = 8 meters, height = 4 Newtons.

And Kinetic energy is E = 1/2 M V^2

You get 6 for mechanical

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.
