Question

v=u+at where v=final velocity ;u=initial velocity;t=timeand 'a' is acceleration gives velocity acquired by a body in time 't' and s=ut+1/2at^2 give displacement of the body in time 't'. the initial and final velocity of car in m/sec are

Answer 2

Answer:

We know acceleration (a) = rate of change of velocity

                                         

                                          =  

timeinterval

changeinvelocity

​

 

                                         

                                          =  

timeperiod

finalvelocity−initialvelocity

​

   

                                         

                                          =  

t

v−u

​

 

∴a=  

t

v−u

​

ora×t=v−u

or at = v - u or at + u = v

∴ v = u + at
