A worker drives a spike into a rail tie with a 2.00-kg sledgehammer. This caused the internal energy of the hammer and spike to
increase by 1,250 Joules. If one half of the hammer’s kinetic energy is converted into the internal energy of the hammer and spike, what was the hammer’s speed when it hit the spike? In your computations, for the mass, use the mass of the hammer only.
Answer: I would say the object with the Lower velocity because Lighter with Higher velocity makes it heavy, velocity is how heavy something is so the lighter it is the less difficult it will be to catch.
