Use the formula for potential energy (PE = mgh), and solve for height/second (note that Watt is joule/second). Since this is the vertical component of the speed, you must next use trigonometry to solve for the total speed.
In an air flow the pressure above the kite is lower and the pressure under the kite is greater; as a result the kite ascend to lower pressures.
When air is forced to ascend because it has come into contact with a mountain or some other raised geographical feature, also called orographic lifting.
The airtight bag was sealed at a lower level. As you ascend, the air pressure becomes less outside, and the air in the bag expands. As it expands, the bag puffs up. Go too high, and the bag will pop. I have driven to the top of Mt Evans Colorado, and at 4350 meters the bag WILL pop!
For flight to be achieved then you must create a force of lift greater than the weight of the glider. this is achieved by the use of an airofoil. ie the wings of the plane. as an airofoil travels through the air the leading edge cuts the airflow. air flowing over the top of the wings travels faster than the air under the wing Faster air = Lower pressure. As there is lower pressure above the wing the force of lift is created. However to create this airflow the glider must be traveling forward at a sufficient speed to create sufficient lift. Being a form of non powered flight it cannot do this alone. that is why it is towed to to the required altitude. Unhitched, And allowed to fall at a controlled speed (glide) downward . to control the speed at which the glider falls, the pilot uses the pitch of the plane. nose up slows descent, nose down increases rate of descent, but also allows you to pick up forward velocity which can be used to re ascend.
In matters of height i will assume you are talking about a rather size-able mountain, along the lines of something like Mt. Rainier In Washington state. or Mt. Saint Hellens ( before she blew her top ) The reason the top of a mountain is colder than the bottom is quite simple. The air you breathe is called Atmosphere the closer to the surface of the earth the denser the Atmosphere. As you ascend a mountain, or gain altitude the Atmospheric Pressure reduces. This reduction in the density of the atmosphere does not allow for the storage of the same amount of heat as lower altitudes. There are many layers of atmosphere, and some Mountains can penetrate several of them. I have included a link to an image pulled from Google image search to further illustrate. See Related Link
