Final answer:
Objects thrown from windows are influenced by a combination of forces, including the force of the throw, gravity, motion of the vehicle, air resistance, and wind from larger vehicles and extended side mirrors.
Step-by-step explanation:
When objects are thrown from windows, it is due to a combination of forces. The force of the throw propels the object forward, while the force of gravity pulls it towards the ground. This motion is influenced by the motion of the vehicle and the air resistance acting on the object. Objects thrown from windows can also be influenced by wind from larger vehicles and extended side mirrors, which can create blasts of wind that push the object in a certain direction.
