Question

An object is dropped from a clif if it reaches the ground in 10 seconds . Calculate the velocity with which it touches the ground if it falls with an acceleration of 10m/s.

Answer 1

Dear Student,
$$\begin{gathered} u=initialvelociy \\ v=finalvelocity \\ a=g=acceleration=10m/s \\ t=time \\ finalvelocitywhenitreachesground \\ v=u+at \\ \sin cetheobjecthasbeenreleased, \\ therefore \\ u=0m/s \\ :v=at=10\times 10=100m/s \end{gathered}$$
