One more assumption
Temperature remains constant in both scenarios
First
b) No atmosphere. If a superball retains about 95% of its energy after each bounce then it will have bounced about 40 times before the retained energy becomes vanishingly small
a)Atmosphere . Wind resistance will will limit terminal velocity. Failed parachutists are reputed to hit the ground at about 125 mph. Superballs are a bit more aerodynamic so say 150mph as round ball park. Then as it bounces up wind resistance cuts in again, and again as it falls so its not going to do so many bounces
You could probably building tall enough for the ball to reach terminal velocity and check it out. Alternatively you could do the math for case a). which is less dangerous.

if the super ball was resistant to the freezing it would reach a terminal velocity and would not continue accelerating infinitely. So whatever this speed is, which is based on the cross sectional area of the ball, would be the speed of the ball when it hits the pavement. If air resistance is neglected and it wont freeze or break on impact by some crazy phenomena, the ball would ideally bounce back to its original height and would bounce an infinite amount of times

ZERO

Super Balls will break on impact because
1) going way to fast to survive impact
2) Assumption(B) 10 miles up it's very cold so ball will be frozen
3) Assumption(A) 10 Miles up is cold, will have too much speed and burn up on re-entry.

it would never stop bouncing! you'll end up with the universe as a pin ball machine.

a. It depends on it's modulus of elasticity
b. assuming no gravity - once, (it would never come back down)

0 (zero). It would shatter. It would freeze that high up and not have time to defrost and would just shatter! LOL!
