Answer:
Speed of the car is 8.49 m/s
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 :
\(E=\dfrac{1}{2}mv^2\)
\(v=\sqrt{\dfrac{2E}{m}}\)
\(v=\sqrt{\dfrac{2\times 16256\ J}{450\ kg}}\)
v = 8.49 m/s
So, the speed of the car is 8.49 m/s. Hence, this is the required solution.
