Using the physics formula:

v2 = u2 + 2as

v - final velocity

u - initial velocity

a - acceleration

s - distance

When the object leaves the ground it is being slowed down by gravity until it stops so the acceleration equals -9.8m/s2 and as it will stop at 2.5 meters v = 0. U is the value we want to find out:

02 = u2 + (2 *-9.8*2.5)

49 = u2

So the object must leave the ground at 7m/s.

By the way this is ignoring air resistance.

5km is 5000mPrefix 'kilo' is used to denote multiples of meter and uses factor 103 or 1000.In order to convert kilometers to meters value in kilometers have to multiplied by provided factor: 5 kilometers = 5 * 103 = 5 * 1000 = 5000 meters5 kilometers = 5,000 meters.50005000 now leave me alone5000 meters5km = 5000m5000There is 5000 meters in 5 kilometers.5000 meters5000, kilo means 1000 so you can read it as 5 'thousand' meters

The volume of an object does not provide information on its shape, leave alone its dimensions. It could be a sphere, a cuboid, a polyhedron or just an irregular "blob".

In mathematics, identity is a transformation that leaves an object unchanged. In addition and subtraction, the identity element is zero. Adding or subtracting zero to or from a number will leave the original number. In multiplication and division, the identity element is one. Multiplying or dividing a number by one will leave the original number.

The velocity of an object that leaves the ground is the same as the velocity when it hits the ground on the condition that it is only acted on by gravity, that it lands on an equivalent surface to one that it left in terms of potential energy (altitude]. In a closed system energy must be conserved so an object that leaves the ground with a certain quantity of kinetic energy must hit the ground with the same quantity of kinetic energy as gravity its self which also means that given the surface it lands on is the same in potential energy as the surface it left, the object must have the same velocity as E mv^2/2. Of course the object in real life is subject to friction and various contributing factors so it is only true in an ideal case that the object returns to the ground with the same velocity that it left the ground.

A solid object hitting the ground with the force of a meteor would leave a crater, a depression in the ground with a raised edge at the surface, similar to Meteor Crater in Arizona.

It depends, on a variety of factors. The most important is what type of food, and how much. A good average is about 3 hours to leave the stomach, 3 hours to leave the small intestine, and 40 hours to leave the large intestine.

Yes you can leave the hyacinth bulb in the ground. Leave the leaves alone to gather food for next year.

the world line of an object cannot leave its own forward light cone because to do so it would have to travel faster than light. once another object enters the forward light cone of an object, it cannot leave it either for the same reason. The backward light cone is a different matter, but it is in the past. Objects can easily leave the backward light cone and no longer be visible.

It depends on the airplane. i.e. a cessna needs around 70 knots while a Boeing 747 needs around 250 knots.
