Netforce is zero right?
Constant speed is constant velocity.
I'm not sure how to draw this.
How do you draw a net force graph for constant velocity?

Not always - remember that velocity is a vector.

Net force in this case is not zero.
Constant speed doesn't imply a constant velocity because velocity is a vector and in the track, its direction changes. This change in direction implies that the body is being accelerated. In this case it is the centripetal acceleration. It can be calculated knowing the velocity and the radius of the track at the required point.
