if an object is fired at a 20 degree angle and has a horizontal velocity of 30m/s, what is the vertical displacement, how long the ball is in the air, horizontal displacement, original velocity of the ball?

The angle of a projectile's initial velocity determines the initial horizontal velocity. The horizontal velocity remains constant throughout the projectile's motion, while the vertical velocity changes due to the influence of gravity.
The angle of a projectile's initial velocity significantly affects its range. The optimal angle for maximum range is 45 degrees, as it results in an equal vertical and horizontal displacement.
No, the horizontal velocity of a projectile can never exceed the initial velocity. The horizontal velocity is always equal to the initial velocity since there is no acceleration in the horizontal direction.
Air resistance can decrease the horizontal velocity of a projectile, as it acts in the opposite direction of motion. The angle of the projectile may also be affected, as air resistance can cause the projectile to deviate from its intended path.
Yes, the angle of a projectile can be negative if it is measured in the clockwise direction from the positive x-axis. This is commonly seen in mathematics and physics problems, but in real-world situations, angles are typically measured in the counter-clockwise direction starting from the positive x-axis.
