Observe the golfer ball shown in the image. (time, t=7.50 s time from when the ball is hit to the max height.)

If this is the time for the ball to reach its max height, what is the total hang time (from the time the ball is hit to the max height to when the ball hits the ground). (Assume no air resistance or spin.)

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
