1. False: The statement is unclear and contains a typo ("vetorny" instead of "velocity"). Without proper information about the absence of air resistance, we cannot determine whether the horizontal velocity of the projectile increases or not. Therefore, the statement is incorrect.
2. False: The statement is incomplete and contains a typo ("pojot" instead of "point"). It is not clear what is meant by "aero acceleration." A bell thrown upward will experience a deceleration due to the gravitational force acting against its motion. Therefore, the statement is incorrect.
3. True: The gravitational force is indeed responsible for the vertical motion of a projectile. Gravity causes the projectile to accelerate downward.
4. False: The initial speed of the projectile does affect its horizontal range. A higher initial speed will result in a longer horizontal distance traveled by the projectile.
5. False: The optimal angle for the farthest range of a projectile depends on various factors such as initial speed, launch height, and the presence of air resistance. It is not always 45 degrees. The angle that maximizes the range can vary and needs to be calculated based on specific conditions.
