Q28:


28. The velocity of a particle increases from u to v in time t during which it covers a distance s. If the particle has a uniform acceleration, then which one of the following equations does not apply to the motion? 


1   2 s   =   v + u t 2   a =   v - u t 3   v 2   = u 2 - 2 a s 4   s = u + 1 2 at t
 

Dear Student,According to third equation of motion,v2=u2+2aSso the equation given in option (3) is incorrect.Regards
