Question
![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

V(t) = V-2kt + vỗ
O c. V(t) = v-2kt + vo
O d. v(t) = vo e kt](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0fe21445-4f7a-45aa-9584-220ed9df356d%2Fec8671f6-7461-4829-b646-20084f7b62d6%2Fbdwaixp_processed.jpeg&w=3840&q=75)
