Answer:
Explanation:
Given
-- Mass of the boy
-- Mass of the girl
-- Acceleration of the girl towards the boy
Required
Determine the acceleration of the boy towards the girl (
)
From the question, we understand that the surface is frictionless. This implies that the system is internal and the relationship between the given and required parameters is:
Substitute values for 
and 
Make the subject
<em>Hence, the acceleration of the boy towards the girl is 1.446m/s^2</em>

For the average speed of blood flow in the major arteries of the body is mathematically given as
v2 = 117.29m/s
<h3>What is the average speed of blood flow in the major arteries of the body?</h3>
Generally, the equation for the average speed is mathematically given as
A1 v1 = A2 v2
(pi r1^2) v1 = A2 v2
(3.14x(1.4)^2 )x 40 = (2.1) xV2
v2 = 117.29m/s
In conclusion, the average speed of blood flow
v2 = 117.29m/s
