Question
Using this table can you answer the questions below?
Calculate the fall time of the filters assuming no air resistance. How does this fall time compare with the average fall times of the single and multi-filters?
Why does the combination reach a higher velocity? To answer this question, use your free body diagram of the falling filter and Newton?s second law to write an equation for the net force on the falling filter. Solve this equation for the acceleration and note how it depends on the mass of the falling object.
Conclusions
Explanation / Answer
height of object
=1.52m
for 1 and 3 filters
assuming free fall condition
h=0.5gt2
1.52*2/9.8 =t2
t=sqrt(0.31)
=0.556 seconds
average of first filter
time=2.30 seconds
average of 3 filter
time=1.44 seconds
average time is greater than normal time
for this average time height may be more for free fall
by using this condition
find velocity
after accelration for normal and average times
find net force on filter according to newtons second law
