Question

Angular Momentum Help Needed!

Answer 1

This is strangest problem I've ever seen. I have no idea where to start...

Answer 2

Do you have any idea? @yrelhan4

Answer 3

i think i do. give me some time.

Answer 4

hmm.
step 1: convert rev/min into rad/sec

step 2: find the force exerted by the gas.
F=dP/dt = vdm/dt

step 3: find the torque due to ejection of gas due to both the nozzles. = 2F.r

step 4: put this equal to I*alpha where I is moment of inertia and find alpha

step 5: apply w(final) = alpha*t and find t.

Answer 5

This has nothing to do with angular momentum, lol. Thanks.

Answer 6

haha. no. you're welcome.
