Which will hit the ground first a ball thrown horizontally at 2 meters per second off a building 20 m high or a ball dropped by a hand at the same height?
They should reach the ground together, since their initial vertical speed is the same, namely zero.

iron bar first
How high does the bounciest ball bounce?
The bounciest balls are the so-called bouncy balls, made of compressed synthetic rubber. These balls have an unusually high coefficient of restitution (inverse momentum) that allows them to return to up to 92% of a dropped height, and to utilize thrown force to reach extraordinary heights. Another generic name for the balls is "super balls," originally a trademark name for a 1964 invention first sold by the Wham-O toy company in 1966.
How is it that A ball is projected straight up from the ground with a speed of 7.61 meters per second To what maximum height will the ball go when gravity equals 9.80 meters per second squared?
Initial upward speed = 7.61 m/sFinal upward speed (at the point of maximum height) = 0Time to reach maximum height = (7.61) / (9.8) = 0.77653 secondAverage speed during that time = 1/2 ( 7.61 + 0) = 3.805 m/sHeight = 3.805 x 0.77653 = 2.9547 meters (rounded) = about 9.7 feetDoesn't seem like much of a height for a strong toss; but the math looks OK.

1.75 ft
How high will a basketball bounce if dropped?
If we knew from what height the ball, when dropped, would reach its terminal velocity, and if we knew the percentage of rebound the ball would give, we could then be certain. I can only guess that a basketball will rebound approximately 75% of the height from which it is dropped, and if the height at which it would reach terminal velocity is maybe 300 feet, the ball would bounce back up to 225 feet. Just a guess! A basketball has an elasticity (or "bounciness") of about 56 percent.I'm not sure there's a theoretical limit. In practice, of course, there would be one: when the velocity of the ball impacting the ground is so great the ball explodes rather than bouncing. But you'd have to fire it out of some kind of basketball cannon to get it moving that fast.The official standard for ball inflation is that the ball should bounce roughly 75% of its drop height (specifically, between 49" and 54") when dropped from 6 feet. If you're referring to just the height a dropped ball could bounce and you're not throwing it down with some kind of basketball-downward-hurling machine, you could calculate the theoretical bounce height by figuring out what terminal velocity is for a basketball, calculating how high you'd have to drop it from (assuming no atmosphere) to achieve that velocity, and then multiplying by 0.75. I'm not going to do it for you, because I'm not actually all that interested in the answer, but that's how you could do it if you are.

Does the mass of the ball affect how high it bounces?
a ball can never bounce over the height from which it was bounced unless u aplly a force. The factors that affect the bounce of a dropped ball include the height from which it is dropped; the force applied to it, if any, when dropped; the acceleration of gravity, which is different depending upon what planet you're one; the elasticity of the ball; the density of the atmosphere, which affects "air resistance"; and the rigidity and elasticity of the surface on which the ball bounces. weight also affect the bounce height.
