A1423 kg car is traveling down the road at 105.0 km/h. while traveling at this rate of speed, what is the kinetic energy of this vehicle in kilojoules?

605.3 kilojoules First, convert the 105.0 km/h to m/s 105.0 km/h * 1000 m/km / 3600 s/h = 29.16666667 m/s Now calculate the energy using the E = 0.5 M V^2 formula E = 0.5 * 1423 kg * (29.16666667 m/s)^2 E = 711.5 kg * 850.69 m^2/s^2 E = 605269.0972 (kg m^2)/s^2 E = 605269.0972 J E = 605.2690972 kJ Rounding to 4 significant figures gives 605.3 kilojoules

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.
