  • Mass=m=14kg
  • Velocity=v=6m/s


\\ \sf\longmapsto K.E=(1)/(2)mv^2


\\ \sf\longmapsto K.E=(1)/(2)(14)(6)^2


\\ \sf\longmapsto K.E=7(36)


\\ \sf\longmapsto K E=252J

Answer:


252J

Step-by-step explanation

Formula to find the kinetic energy is,


E_(k) = (1)/(2) m {v}^(2) \\ \\ m = mass(kg) \\ v = velocity( {ms}^( - 1) )

Lets solve


E_(k) = (1)/(2) m {v}^(2) \\ = (1)/(2) * 14kg * 6 {ms}^( - 1) * 6 {ms}^( - 1) \\ = (504)/(2) \\ = 252J

hope this helps you.

Let me know if you have any other questions:-)
