Answer:
Relation between kinetic energy of truck and kinetic energy of car is given as
Explanation:
As we know that mass of truck is four times the mass of car
and the speed of truck is double that of speed of car
now we have kinetic energy of the truck is given as
similarly kinetic energy of car is given as
now from above two equations we have
so we have
