Answer:
Time taken, t = 0.16 seconds
Explanation:
Given that,
Initial speed of blood, u = 0
Final speed of blood, v = 25 cm/s = 0.25 m/s
Distance, d = 2.1 cm = 0.021 m
Using first equation of motion as :
v = u + at
u = 0
[tex]v=at\\0.25 =at[/tex]
Let t is the time taken. Using second equation of motion as :
[tex]d=ut+\dfrac{1}{2}at^2[/tex]
[tex]d=\dfrac{1}{2}at\times t[/tex]
[tex]t=\dfrac{2d}{at}[/tex]
Since, at = 0.25
So,
[tex]t=\dfrac{2\times 0.021}{0.25}[/tex]
t = 0.16 seconds
So, the time taken by the blood to accelerate is 0.16 seconds. Â Â
