Drake Glau Posted December 21, 2011 Report Share Posted December 21, 2011 a) into all the metal crunching up as your car smooshes together.b) Throws a heavy ball AT you? You would move in the direction the ball is travelling since when you catch the ball/ball hits you, most of the momentum transfer into your body.c) Throw the backpack. You project a force forward, newton says you also had a reaction force applied back on you thus pushing you back. Reply Link to post Share on other sites More sharing options...
