A friend and i have been arguing for weeks initially starting when we were driving in hisi car and i had a small american football, i contended that if i were to throw it out the car window, at the point of release it would be doing the speed of the car + the speed of my throw relative to the ground and would travel forward a few meters due to the previous force applied through the car/hand into the ball, Is this the case? My friend replied that in a "perfect release mechanism" the moment the ball is released from a moving yet perfect release mechanism all forces on it are nullified instantly and it would drop perfectly straight down from the exact point of perfect release, my contension is that due to the release mechanism be it perfect or imperfect being in motion at the time of release that force will be transfered into the ball relative to the ground? I accept his argument that the imperfect release will affect thing such as trajectory, but he also seems to be arguing that this perfect release nullifies the speed the ball had been traveling at in the instant of release? Can someone please settle this once and for all? I am i completely wrong?
