Plz help A person generates 3000 J of Kinetic Energy and has a mass of 100 kg. What is their velocity?​

3000 J/100 kg = 30 kg/J

hope this helps

Explanation:

K.E. = 1/2 mv2

3000= 1/2 *100 *v2

60= v2

v = 7.7459

specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.

explanation:

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

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

c) both a and b.
