Answer 2

Explanation:

• we have displacement(s)=(average velocity/2)*time(t)
• => s=(v+u/2)*t..............................................(i)
• now we have acceleration formula=> a=(v-u)/t....................(ii)
• now in equation (i), v= (2s-ut)/t ........................(iii)
• now by putting value of 'v' from equation (iii) in equation (ii), we get,
• $a=\frac{\frac{2s-ut}{t}-u }{t}$
• $\frac{2s-2ut}{t^{2} } =a$
• $2s-2ut=at^{2}$
• $2s=2ut+at^{2}$
• $s=ut+\frac{1}{2} at^{2}$ (Ans.)
• here,s=displacement
• u=initial velocity
• t=time
• v=final velocity
