A ball is equipped with a speedometer and launched straight upward. The speedometer reading 4 seconds after launch is shown at the right. At what approximate times would the ball be moving upward and display the following speedometer readings?

Answer: buoyancy forceexplanation: in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

You can find results and justify them? you can test your hypothesis

That depends on what kind of environ meant it is in  in space it has the same force that was applied when the velocity was gained
