## Speed

## Acceleration

____________________________GivenTo findConceptused~ Here the concept of

motions equatîonis used. Time, acceleration, initial velocity is given. We have to find the final velocity. Simply súbsitúte the value in first equation of motion.SolutionWe know that Motion’s 1st equatîon of motion is:-[tex]{ \underline{ \boxed{ \sf{ \red{V= u+at}}}}}[/tex]

where»v denotes final velocity»u denotes initial velocity»a denotes acceleration»t denotes time[tex]\sf{\implies V=0+4 ×5}\\ \\\sf{ \implies\pink{ V= 20 m/sec}}[/tex]

⚘

Therefore the final velocity is 20 m/sec.____________________________Moretoknow[tex] \sf{➢ Average \: speed = \frac{Total \: distance}{time}}[/tex]
