gps-8 - 2 situations

[crew]

this is a play that i have no idea what the correct answer is. please help with references NF/nc2a/nba it doesnt matter.

1. a1 drives to the basket takes 2 steps jumps and attempts a 2 handed dunk. a1 does not get up high enough to dunk but he pins the ball on the rim(does not let go) and comes to the floor with the ball.

2. similar play. a1 jumps to try a shot attempt from directly under the backboard. a1 gets the ball pinned to the bottom of the backboard(does not let go) and comes to the floor with the ball.

what would be the proper call in these 2 situations?

for college and nba consider the effect the play may have on the shot clock in situation #1.
