Answer:
The kinetic energy of car 1 is half Kinetic energy of car 2
Step-by-step explanation:
velocity of car 1 is V1 while that of car 2 is V2
From the question:
V1 = V2
If mass of car 1 is m, then mass of car 2 is 2m
E= 1/2mv^2
kinetic energy of car 2 = 1/2×2mv^2 = mv^2
kinetic energy of car 1 = 1/2mv^2
Therefore, Kinetic energy of car 1 is half kinetic energy of car 2
