They should reach the ground together, since their initial vertical speed is the same, namely zero.

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.
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.
A 60-cm height setting will cause the 35 g car to reach the egg in 1.88 s.
After the 7th bounce, the ball will reach a height of 1 meter. This is because after each bounce, the ball reaches half of its previous height. So, after 1 bounce it reaches 64 meters, after 2 bounces it reaches 32 meters, after 3 bounces it reaches 16 meters, and so on, until it reaches 1 meter after the 7th bounce.
After each bounce, the ball reaches half of the height from which it was dropped. Since the ball was initially dropped from 10 feet, on the first bounce it will reach 5 feet, on the second bounce it will reach 2.5 feet, on the third bounce it will reach 1.25 feet, and on the fourth bounce it will reach 0.625 feet.
When an object is dropped from a certain height, the time it takes to reach the ground is independent of the height (assuming no air resistance). Therefore, whether you drop the object from three times the initial height or the original height, it will still take the same time (T) to reach the ground.
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.
Most sycamore tree's reach 30-40 meters.

Both weights will fall at the same rate due to gravity. The acceleration due to gravity is constant regardless of the mass of the object, so both weights will reach the ground at the same time when dropped from the same height.
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.

The average height of a glacier can vary greatly depending on factors such as location, climate, and size. However, most glaciers range in height from a few meters to several hundred meters. Some of the largest glaciers, like those in Antarctica and Greenland, can reach heights of over 3,000 meters.
