6. [1/2 Points] DETAILS PREVIOUS ANSWERS MI4 6.4.037. MY NOTES PRACTICE ANOTHER (a) Check all of the following that are correct statements, where E stands for ymca. Read each statement very carefully to make sure that it is exactly correct. The definition of work is W = . At speeds close to the speed of light, kinetic energy is approximately equal to (1/2) my2. The definition of work is W = 1I. The energy principle can be written AEsys = Wsurr The definition of work is W = FAX + FAy + FAz. The definition K = E - mc2 is valid even for speeds near the speed of light. The energy principle can be written Esys,f - Esys,i + Wsur (b) An object with mass 100 kg moved in outer space. When it was at location its speed was 14.5 m/s. A single constant force N acted on the object while the object moved to location m. What is the speed of the object at this final location? final speed = 17.61 X m/s Additional Materials eBook
