[tex] \bf \underline{Given : }[/tex]
- Initial velocity,u = -2 m/s
- Final velocity,v = -10 m/s
- Time taken, t = 4 seconds
[tex] \bf \underline{To \: find \: out : }[/tex]
Find the acceleration ( a ) .
[tex] \bf \underline{Solution : }[/tex]
We know that,
[tex] \sf \: Acceleration = \dfrac{v - u}{t} [/tex]
Substituting the values in the above formula, we get
[tex] \implies \sf \: Acceleration = \dfrac{ - 10 - ( - 2)}{4} [/tex]
[tex] \implies\sf \: Acceleration = \dfrac{ - 10 + 2}{4} [/tex]
[tex] \implies \sf \: Acceleration = \cancel \dfrac{ - 8}{4} [/tex]
[tex] \implies\sf \: Acceleration = - 2 \: ms {}^{ - 2} [/tex]
Hence,the acceleration of a body is -2 m/s².
