Lut initial Velocity be ( u ), Rinal velocity ( =(1-3 / 4) u=44 u ) [ begin{array}{l}=u+a t=frac{u}{u}=u+a t_{0} quad lambdaend{array} ] ofinal Vubcity is o at t [ begin{aligned} therefore quad O=& l_{t}+a t Rightarrow quad c=left(frac{3 u}{4 t_{0}}right) t=0 & Rightarrow t=frac{4}{3} t_{0} end{aligned} ]
