Answer:
m = 2301.8 [kg]
Explanation:
This problem can be solved in an easy way using the definition of kinetic energy, in this way you can clear the mass, depending on the known variables.
![E_{k}=0.5*m*v^2\\replacing\\\\9023 = 0.5 *m*(2.8)^2\\m = 2301.8[kg]](https://tex.z-dn.net/?f=E_%7Bk%7D%3D0.5%2Am%2Av%5E2%5C%5Creplacing%5C%5C%5C%5C9023%20%3D%200.5%20%2Am%2A%282.8%29%5E2%5C%5Cm%20%3D%202301.8%5Bkg%5D)
The best answer to the question that is being presented above would be the speed. Since speed is characterized by distance/time, the 150 km/h is one example of a measurement of speed. Thus, the correct answer should be letter b. which is speed.
