Question
Transcribed Image Text:The brake mechanism used to reduce gun
recoil consists of a piston attached to a barrel
moving in a fixed cylinder filled with oil. As
barrel recoils with initial velocity vo, piston
moves, and oil is forced through orifices in a
piston, causing piston and cylinder to
decelerate at a rate proportional to their
velocity. Determine v(t).
Piston
Oil
a =-k/v
O a. v(t) = vo ekt
Ob.
V(t) = V-2kt + vỗ
O c. V(t) = v-2kt + vo
O d. v(t) = vo e kt
