I used "2uSin(theta)/g" but the values that I put for "u" were like u2 > u1. And this is why I'm not sure of my answer and I doubt that it may be wrong.Qwertywerty said:

Trajectory refers to the path followed by an object as it moves through space, under the influence of external forces such as gravity or air resistance.
The initial velocity of a projectile determines the direction and speed at which it travels, and thus plays a crucial role in determining its trajectory. A higher initial velocity will result in a longer and flatter trajectory, while a lower initial velocity will result in a shorter and steeper trajectory.
The angle of projection, also known as the launch angle, has a significant impact on the trajectory of a projectile. The trajectory will be longest and flattest when the angle of projection is 45 degrees, and will decrease in length and steepness as the angle deviates from 45 degrees.
The main difference between the trajectories of two projectiles launched at the same time with different initial velocities is the shape of the path. The projectile with a higher initial velocity will have a longer and flatter trajectory, while the one with a lower initial velocity will have a shorter and steeper trajectory.
Air resistance, also known as drag, can significantly affect the trajectory of a projectile. It acts in the opposite direction of the projectile's motion and can slow it down, causing the trajectory to be shorter and steeper than expected. The effect of air resistance can be minimized by increasing the initial velocity of the projectile.
