Hi, I'm wondering what would happen if a tennis ball was dropped from the tennis court on the Dubai hotel which is very high, about 80 stories I think. Would the ball bounce or would it not survive the impact, and if it hit someone below would they survive the experience? Thanks

Nothing spectacular would happen.   Due to air resistance the tennis ball would reach a terminal velocity of about 100 km/hour.  The ball would happily bounce unharmed.    To put it in perspective, a good pro tennis player can serve at 150 km/hour.  As for a person being harmed, how would you like to be hit in the head by a 100 km/hour tennis ball?
