O Hint Check Answer on 1 of 27 It is generally a good idea to gain an understanding of the "size" of units. Consider the objects and calculate the kinetic energy of each one. A ladybug weighing 28.5 mg flies by your head at 4.09 km/h. A 6.55 kg bowling ball slides (not rolls) down an alley at 22.9 km/h. A car weighing 1280 kg moves at a speed of 57.5 km/h. about us careers privacy policy terms of use contact us help MacBook Pro 24 & 41 5 8. T Y U H J K M F.
