If a 4 kg object is moving 5 m/s, how much kinetic energy does it have?

K.E = 50 J  

Explanation:

Given data:

Mass of object = 4 Kg

Speed of object = 5 m/s

K.E = ?

Solution:

Formula:

K.E = 1/2mv²

by putting values,

K.E = 1/2 × 4 Kg × ( 5m/s)²

K.E = 1/2 × 4 Kg ×25 m²/s²

K.E = 50 J   (Kgm²/s² = J)

answer: the blood-brain barrier is a layer of specialized membranes and cell processes designed to keep undesirable substances from passing from the bloodstream into the precious tissues of the brain. while the blood-brain barrier does keep most bad things out of the central nervous system, it is not impermeable.
