While walking and then running at a constant speed with the same ball, you want to release each ball in time for it to land in a target. In order for the ball that you run with to hit the target, when would you have to release the ball you run with relative to the release of the ball you walk with?

at the same time as the ball you walk with

earlier than the ball you walk with

whenever you feel like it

later than the ball you walk with
