Answer:
Speed of the car is 8.49 m/s
Step-by-step explanation:
It is given that,
Mass of the car, m = 450 kg
Kinetic energy of the car, E = 16256 J
We need to find the speed of the car. The kinetic energy of the car is given by :



v = 8.49 m/s
So, the speed of the car is 8.49 m/s. Hence, this is the required solution.
