What is the mass of an object with a momentum of 250 kgm/s and a velocity of 5 m/s?

Momentum = mass x velocity
So mass = momentum / velocity
Therefore 250 / 5 = 50 kg

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.
