I would agree in that it does no work. But it does change the energy vector. Explaining why that is important to golf is a place we do not want to go I would guess?
Maybe because very few golfers can run 100 mph? Or golf carts go that fast.
Wow, a 100+ mph golf cart. Just put an sweet spot on the front bumper, tee it high and steer (normaly bad-good here). Tough to shape shots though.
