Answer:

When an object is projected from rest at an upward angle, its initial velocity can be resolved into two components. The upward velocity undergoes constant downward acceleration which will result in it rising to a highest point and then falling backward to the ground. ...

Buoyancy (/ˈbɔɪənsi, ˈbuːjənsi/)[1][2] or upthrust, is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus the pressure at the bottom of a column of fluid is greater than at the top of the column. Similarly, the pressure at the bottom of an object submerged in a fluid is greater than at the top of the object. The pressure difference results in a net upward force on the object. The magnitude of the force is proportional to the pressure difference, and (as explained by Archimedes' principle) is equivalent to the weight of the fluid that would otherwise occupy the submerged volume of the object, i.e. the displaced fluid.
