The calculation of kinetic energy uses the formula, ke = 1 2 mv2. identify the unit that is required for mass and velocity, respectively, to determine the kinetic energy in joules. a) mass in g, velocity in m s b) mass in kg, velocity in m s c) mass in g, velocity in km hr d) mass in kg, velocity in km hr

So the answer  is B.  because the mass have  Kg as a international unit and velocity is m/s, they are  international units in physics.

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

0.11 m/s and 0.28 m/s should be correct
