Question

Height of fall 1.52 meters

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.

Explanation / Answer

considering the first filter

average time required to go down

t=2.3seconds

intial velocity=0

V2-U2=2as

accelration is positive=g=9.8m/s2

V=sqrt(2*g*h)

=sqrt(2*9.8*1.52)

=5.45m/s

accelration of the ball

V=U+at

a=V/t

=5.45/2.3

=2.373m/s2

Fnet=ma

a=Fnet/m

for 3 filters

t=1.44seconds

a=V/t

=5.45/1.44

=3.78m/s2

for dependence on mass

write newtons 2 law

Fnet=ma
