Without air resistance . . .

           Distance  =  1/2 g T²

               500 m  =  (1/2) (9.8 m/s²) (T²)

               500 m  =  (4.9 m/s²) (T²)

Divide each side by   (4.9 m/s²)  :

                  T²  =  (500 m) / (4.9 m/s²)

                       =     102.04 s²

                   T  =  √ (102.04 s²)

                       =       10.1 seconds

Are temperature and thermal energy the same thing justify your answer
Sever21 [200]
Temperature is the measurement of the average energy of the particles in a solid, liquid or gas and thermal energy is the total energy in a set amount of solid, liquid or gas. Therefore, the temperature and thermal energy is not the same thing. They are both about the particle theory, which is a theory that all particles of solid, liquid or gas are always in motion. But the difference between the two is that temperature is the "measurement" of the particles in a solid, liquid or gas and the thermal energy is the total energy in a set amount of solid, liquid or gas.
