An object is thrown vertically downward. What is the acceleration experienced by the object?

Answer»

Solution :We know that when the object falls towards the Earth, it experiences acceleration DUE to GRAVITY `g=9.8ms^(-2)` downward. We can choose the COORDINATE system as shown in Ground the FIGURE.
The acceleration is along the NEGATIVE y direction
`veca=g(-hatj)=-ghatj`
