Question

If an 10 kg object has a potential energy of 125 J, what velocity would it be right before it hit the ground?

Answer 1

By potential energy do you mean gravitational potential energy, as in the object is falling?

Answer 2

i think it is while the object is falling

Answer 3

The gravitational potential energy is being transferred into kinetic energy so,
Eg=Ek
Eg=0.5m(v^2)
125 J = 0.5*(10 kg)*(v^2)
125 J = 5 kg * (v^2)
125J/ 5kg = v^2
25=v^2
5 m/s = v
