6.34 m/s

Explanation:

Given that,

A basketball player leave the ground to rise 2.05 m above the floor  in an attempt to get the ball.

We need to find the velocity must a basketball player leave the ground. Using equation of kinematics as follows :

As it leaves the ground, its final velocity, v = 0

a = -g (opposite to gravity)

or

u = +6.34 m/s

So, the basketball player must leave the ground with a velocity of 6.34 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.
