- Multiple ChoiceJill can throw a ball at a speed of 80mph, consistently, on the ground. She gets into the back of a truck, which drives down the road in the direction at 30mph. Jill faces the back of the truck and throws a ball. According to Galilean relativity, what is the component of the velocity of the ball relative to the ground?656views
