Please Help A 6.0 kg cart moves at a velocity of 12 m/s. The cart bounces off a wall causing it to rebound in the opposite direction at a speed of 18 m/s.

What is the change in the earth's momentum? At for collision is 0.45 earths is the average force from the wall on the cart?

Delta t for collisions is 0.4s

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.
