 \red{ \boxed{K.E= \frac{1}{2}m  {v}^{2} }}

 \purple{ \sf{where : }}

  • m  \: \tt{is \: mass}
  • v \: \tt{is \: velocity}

  \purple{ \sf{here : }}

  • m = 400 \: g = 0.4 \: kg
  • v = 10 \: m {s}^{ - 1}

 \implies K.E= \frac{1}{2}  (0.4) {(10)}^{2}

\implies K.E= (0.2) (100)

 \orange{\therefore K.E= 20 \:  J}

HOPE IT HELPS!!
