Which of the following cars have the most kinetic energy

mass = 4 kg

velocity = 5 m/s^2

Mass= 2kg

Velocity = 7m/s^2

mass = 6 kg

velocity = 4m/s^2

Mass = 8 kg

Velocity = 3 m/s^2

By the equation of kinetic energy,

                                         K.E =

Where,

            K.E is kinetic energy

            m is mass

            v is velocity

Directly substitute the variables in the equation,

                                       K.E =

Simplify the equation,

                                       K.E = 50 J

 Directly substitude the variable in the equation,

                                        K.E =

Simplify the equation,

                                        K.E = 48J

Substitute the variables in the equation,

                                         K.E =

Simplify the Equation,

                                         K.E = 36J

Substitute the variable,

                                        K.E =

Simplify the equation,

                                        K.E = 49J

As you can see that the highest value of kinetic energy is of Blue SUV thus it will be out answer.
