for Block B, we just have the force from block A acting on it
F(ab)d= .5(1)vf² - .5(1)(2²)
F(ab)d= .5vf² - 2
Block A, we have the force from the hand going in one direction and the force of block B on A going the opposite direction
10-F(ba)d = .5(4)vf² - .5(4)(2²)
10-F(ba)d = 2vf² - 8
F(ba)d = 18 - 2vf²
now we have two equations:
F(ba)d = 18 - 2vf²
F(ab)d= .5vf² - 2
since the magnitude of F(ba) and F(ab) is the same, substitute and find vf (I already took into account the direction when solving for F(ab)
10-.5vf² + 2 = 2vf² - 8
12 - .5vf² = 2vf² - 8
20 = 2.5vf²
vf² = 8
they both will have the same velocity
KE of block A= .5(4)(2.828²) = 16 J
KE of block B=.5(1)(2.828²) = 4 J</span>

The acceleration of gravity is proportional to the planet's mass, and inversely proportional to the square of the planet's radius.
So on this particular planet, the acceleration of gravity will be
(Earth gravity) x ( 3.57 / 1.61²)
That's (9.81 m/s²) x (1.377) = <em>13.51 m/s²</em>
A clinician actually apply epithelial absorption techniques through the following below:
- Oral meds.
- Inhalation
- Injections
<h3>What is E
pithelial absorption?</h3>
This is referred to as the process which is responsible for the absorption of various types of nutrients from the intestinal lumen and transporting them across the epithelium by various organs in the body such as the kidney etc to the blood vessels such as capillaries.
The various ways in which a a clinician would actually apply the epithelial absorption techniques is through oral meds like in the case of water and electrolytes and also in the case injections via insulin shots etc.
