## The Attempt at a Solution

I have solved equation for r(t) and i have arrived at:

Since the Bullet is moving freely the net forces acting on the bullet must be zero.

Radial component of the force is obviously zero since both Radial acceleration and centripetal acceleration are same and acting in opposite direction. In the tangential acceleration radial acceleration is zero since the pipe is rotating at constant speed.

But i am not understanding how coriolis force is becoming zero in tangential component.

Rather i am unable to find reason why coriolis force is zero!

Any insight into these concepts will be really helpful!

Thanks a lot
