Momentum

Momentum Formula: P = mv

P is momentum (in kg · m/s)m is mass (in kg)v is velocity (in m/s)Explanation:

Step 1: Define

m₁ = 87.2 kg

v₁ = 2.87 m/s

m₂ = 0.0520 kg

v₂ = 789 m/s

Step 2: Find Momentums

Football Player

Substitute [MF]:                    P = (87.2 kg)(2.87 m/s)Multiply:                                P = 250.264 kg · m/s

Bullet

Substitute [MF]:                    P = (0.0520 kg)(789 m/s)Multiply:                                P = 41.028 kg · m/s

Step 3: Find difference

Define equation:                    P₁ - P₂Substitute:                              250.264 kg · m/s - 41.028 kg · m/sSubtract:                                 209.236 kg · m/s

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.

The particles of the gas inside the ball heats up, bouncing off each other and spreading farther apart.hope my answer has you : )
