The K.E. of car will be "784000 J".
Given values are:
Mass,
Velocity,
→ The Kinetic energy will be:
= [tex]\frac{1}{2} mv^2[/tex]
By putting the values, we get
= [tex]\frac{1}{2}\times 2000\times (28)^2[/tex]
= [tex]\frac{1}{2}\times 2000\times 784[/tex]
= [tex]2000\times 392[/tex]
= [tex]784000 \ J[/tex]
Thus the above answer is correct.
