While the balloon is ascending, everything in the balloon is ascending at the same velocity. It's no different if you pick up a rock and throw it straight up at 13 m/s.carlitos_30 said:Homework Statement
A balloon is ascending at an speed of 13 m/s. At 300 m from the ground a ballast is drop from the balloon. Find the maximum height the ballast reach.
My doubt is: When the ballast is drop ¿it starts falling inmediately?. The solution of the problem implies that the ballast keep ascending for 8,6 m.
Thanks.

It takes gravity a finite duration to arrest the upward motion and bring the velocity to zero, before things begin to fall back to the ground.
How do you know what someone else sees?carlitos_30 said:An observer in the ground would see the ballast fall inmediately, I mean he wouldn't see the ballast ascending for 8,6 meters. That's what I imagine. What's wrong with my imagination?
This is a great example. Thanks.billy_joule said:What about a ball dropped from a car moving at 13 m/s?
If you're watching from the side of the road what speed will the ball be traveling as soon as it's dropped? Will it s stop where it lands? Or continue bouncing down the road?

If you throw a rock straight up at 13 m/s, does the rock stop immediately once it leaves your hand and drop to the ground?
You can imagine many different things, some real, some impossible. We deal with science at PF, not your imagination.
The purpose of the Balloon and Ballast experiment is to determine the maximum height that can be reached by a dropped weight (ballast) when attached to a balloon. This can help scientists understand the principles of buoyancy and gravity.
2.The experiment involves filling a balloon with a known volume of air and attaching a weight (ballast) to it. The balloon is then released and the height at which the ballast drops is measured. This process is repeated with different amounts of air in the balloon to determine the maximum height reached by the ballast.
3.The maximum height of the dropped ballast is affected by several factors, including the weight of the ballast, the volume of air in the balloon, and the atmospheric conditions such as air pressure and wind. The shape and size of the balloon can also have an impact on the experiment's results.
4.The Balloon and Ballast experiment can have various applications in fields such as aeronautics, meteorology, and physics. It can help in understanding the behavior of objects in different atmospheric conditions, and can also be used to test the efficiency of different balloon designs.
5.The results of this experiment can be used to improve the design and functionality of hot air balloons and other air-based transportation methods. It can also provide insights into the behavior of objects in different atmospheric conditions, which can be useful in developing new technologies for weather forecasting and atmospheric research.
