Just a quick question of of curiosity. It's basic physics but I can't remember it Lets say you have two balls of equal mass about 3 meters up on a ledge. You let one drop straight down, it hits the ground and stops. The other one is pushed forwards with a speed of lets say 1m/s and then hits the ground further out and continues to roll. Which ball takes more impact? If I remember correctly, each ball has separate x and y components so they both would land with the same impact, but I am not sure. Can anyone please elaborate? Thank you!
