Hello I'm stuck on two momentum concept problems and can't figure them out, I was hoping someone could provide help. 1.A small truck and a large truck have the same kinetic energies, which truck has the greater momentum? Justify your answer. Well i know Ek=.5mv^2 and that momentum p=mv Ive tried rearranging these into eachother and can't find a clear answer. I think it is the large truck but at the same time the small one will have a greater velocity so I dont know what one will have more momentum. 2. Can an object have kinetic energy but not momentum? Can an object have momentum but no kinetic energy? explain. I said no to both because if you have kinetic energy you have a velocity, and if you have momentum then you have a veolocity therefore kinetic energy. I want to make sure I'm right here though.
