Case-1:-
- Time=1s
- Final velocity=v
[tex]\\ \rm\hookrightarrow v=u+at[/tex]
[tex]\\ \rm\hookrightarrow v=0+3(1)[/tex]
[tex]\\ \rm\hookrightarrow v=3m/s[/tex]
Case-2:-
- Time=3s
[tex]\\ \rm\hookrightarrow v=0+3(3)[/tex]
[tex]\\ \rm\hookrightarrow v=9m/s[/tex]
Case-3:-
- Time=25s
[tex]\\ \rm\hookrightarrow v=0+3(25)[/tex]
[tex]\\ \rm\hookrightarrow v=75m/s[/tex]
