    he head of the sledge hammer weighs 22N and is moving at a speed of 7.6m/s when it strikes a skate.The skate moves 0.025m in to the ground in response. assume that forty % of the hammer kinetic energy is converted to initial kinetic energy of teh skate. apply teh work-energy theorem and obtain teh average resistive force applied to teh skate by the ground

    Yes, I do want to, and it might be kind of a romantic view but I want it because it seems to be the part where there is more creativity when creating theories, but I'm not sure about this part, I just hope. Do you still need help here? If you do can you draw the situation, cause I'm a little confused.

    Oh, thats a tricky one hehehe, many physicist in Brazil end up working at schools teaching teenagers and they are not well paid, even in private schools, but that is here, your educational system is better, so I dont know how it is over there (im assuming you live in the states). But here, if you go to do research (and here this happens mostly on college, not on private companies), you also teach on the university, but my professors say they are well paid. It is not extremely well paid, but its a good amount. If you are a very good physicist though all universities in the world might accept you and you have good chances of being very well paid.
