Answer:
Step-by-step explanation:
First, in millimeters, so the first square is 2025, and the second square is 900. Add those to get 2925 mm. Then, look at the answers. Whichever one has 2925 mm squared first, then a smaller number, that's the one. Therefore, the answer is 2925 mm squared and 29.25 cm squared.
The question here is how long does it take for a falling
person to reach the 90% of this terminal velocity. The computation is:
The terminal velocity vt fulfills v'=0. Therefore vt=g/c,
and so c=g/vt = 10/(100*1000/3600) = 36,000/100,000... /s. Incorporating the
differential equation shows that the time needed to reach velocity v is
t= ln [g / (g-c*v)] / c.
With v=.9 vt =.9 g/c,
t = ln [10] /c = 6.4 sec.
to get the slope of a line all we need is two points off of it, so let's get two points from that table
