Answer:
a. Picture attached
b. V, X
c.
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:
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:
If we reorganize the equations, considering that and
are zero because motion starts from rest , we have:
Finally, the analysis of the result leaves us to understand why the normal heart beat rate varies between 60 and 100 bpm.
