Blood is accelerated from rest to 30.0 cm/s in a distance of 1.80 cm by the left ventricle of the heart. (a) Make a sketch of th

Mila [183]

Answer:

a. Picture attached

b. V, X

c. $t=0.12 s$

d. It makes sense cosidering that a normal heart beat rate is between 60 and 100 beats per minute (bpm).

Explanation:

First we have to identify the unknown of this problem:

$a: acceleration\\t: time$

Considering the characteristics of the problem and that distance and velocity are specified, the acceleration is constant, for that reason we use the equations of uniformly accelerated motion as follows:

$v=v_{0}+at\\ x=x_{0}+ v_{0}+\frac{1}{2}at^{2}$

If we reorganize the equations, considering that $x_{0}$ and $v_{0}$ are zero because motion starts from rest , we have:

$a=\frac{v}{t} \\x=\frac{1}{2}at^{2} =\frac{1}{2}\frac{v}{t} t^{2}=\frac{1}{2} vt\\t=\frac{2x}{v} \\t=\frac{2*1.80cm}{30.0\frac{cm}{s} } \\t=0.12 s$

Finally, the analysis of the result leaves us to understand why the normal heart beat rate varies between 60 and 100 bpm.

what is the magnitude of g at a height above earth surface where free fall acceleration equal 6.5m/s2

ZanzabumX [31]

The magnitude of gravity is expressed in terms of its acceleration. So the magnitude of ' g ' at that altitude is exactly 6.5 m/s^2.

An object that has negative acceleration is definitely doing what?

krek1111 [17]

If an object is consist of a negative acceleration or composed of it, it is likely engaging of having to accelerate in a certain direction in which the direction is heading towards the opposite of the direction that is stated and that is likely to be a positive direction.
