Answer:
Factor by which kinetic energy increase = 4 times
Step-by-step explanation:
Given,
= 15.64 m/s
Initial kinetic energy of the car is given by,
= 183606.46 J
= 31.29 m/s
So, final kinetic energy of car is given by
= 734425.84 J
Now, the ratio of final to initial kinetic energy can be given by,
Hence, the kinetic energy will increase by 4 times.
y=2 and 3/4
