Bump for wasted potential stories :3c

Ok guys, medical school guy here, just for fun I wanted to calculate the force of the impact of a theorethical jump out of a window / snowboard / skateboard
We have a guy with m 75kg, going at theorethically 60km/h straight forward at the top of the arch of the jump, which is 6 meters high, how strong is the impact? is there a way to convert J in a more understandable unit? like, suddenly holding 100 more kgs? Also, let's ignore wind and elasticity of the board/legs/snow, it doesn't have to be perfect

extra fun: would it be possible to calculate the sound produced by said impact? like, knowing the area and material of the objects colliding assuming a perfect flat landing?

infinite thanks, i can't do this on my own, if it was just a vertical drop it would just be J = mass height gravity, but :/
