Question
Particles 1 and 2 of equal mass are thrown vertically upwards at the same initial
velocity vo in a constant gravitational field. Particle 1 is under a negligible air resistance fr = 0
while Particle 2 experiences a resistance of the form fr = mav, where m is the particle's mass, a
is a positive constant, and v is the particle's velocity at any point in time. Show that the ratio
(t2/t1) of the times required for the particles to reach maximum height is given by
t2
avo
= 1-
+ O
t1
2g
2g
where O denotes higher order terms. In the limit a → 0, your result for t2 must approach t1.
