Your answer is 89.56 hope this helps and God bless you
The answer is a, because I need more
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.
If you have to write the equation then it would be "5k + 6.7"
Answer:
65
Step-by-step explanation:
180-115=65
It needs to be a total of 180 so just do what I did :)
