A car with a mass of 1180 kilograms is being driven at 18.2 meters per second when it runs into a tree. What is the change in kinetic energy of the car? Include units in your answer. Answer must be in 3 significant digits.

Respuesta :

The kinetic energy formula is

[tex]K=\frac{1}{2}mv^2[/tex]

Where m = 1180 kg and v = 18.2 m/s.

[tex]K=\frac{1}{2}\cdot1180\operatorname{kg}\cdot(18.2\cdot(\frac{m}{s}))^2=195,431.6J[/tex]

Therefore, the kinetic energy is 195,431.6 Joules.
