Answer:
- Let us assume a body has initial velocity ' u ' and it is subjected to a uniform acceleration ' a ' so that the final velocity be ' v ' after a time interval ' t '. Acceleration is the rate of change of Velocity.Now , by the definition of acceleration , we have :
[tex] \large{ \tt{❃ \: a = \frac{v - u}{t}}} [/tex]
[tex] \large{ \tt{ \dashrightarrow \: at = v - u}}[/tex]
[tex] \large{ \tt{∴ \: v = u + at - - - \tt{ {1}^{st} EQUATION \: OF \: MOTION}}}[/tex]
