suppose u r standing on a skateboard or on in-line skates and u toss a backpack full of heavy books toward....
your friend. what do you think will happen to u and y? explain your answer in terms of newton's third law of motion
For every action there is an equal and opposite reaction therefore you would be pushed backward away from your friend.
Actually if you pushed the backpack away from you at a point above your center of mass then you would recieve a torque (turning) motion which would land you on your butt. If you tossed the backpack below your center of mass (at your knees) you would receive the opposite torque and land on your face.
