Final answer:
Projectile motion calculations require the angle of launch, which is missing from the question provided. Without it, it is not possible to determine the time of flight, maximum height, range, or initial velocity accurately.
Step-by-step explanation:
The student's question involves calculating various parameters related to projectile motion. To find the time of flight, maximum height, range, and initial velocity, one can use the kinematic equations for projectile motion under the influence of gravity. Since the problem states that drag is negligible, air resistance won't factor into the calculations. The key components that need to be found are the vertical and horizontal components of the initial velocity, and then these components are used to find the projectile's flight characteristics.
However, as the question does not give the angle of launch, it is not possible to proceed with the calculations without this crucial piece of information. We can only specify that the horizontal component of the velocity (Vx) will remain constant, and the vertical component of the velocity (Vy) will be affected by gravity, altering over time until the projectile lands.
