select the correct answer. which statement is true for the hang time of a projectile? a. it can be…

Brief Explanations:

The hang - time of a projectile is the time it spends in the air. The vertical motion of a projectile is a free - fall motion with constant acceleration (g) (acceleration due to gravity). The time of flight (T) is determined by the initial vertical velocity (v_{0y}) and the acceleration due to gravity. The formula for the time of flight of a projectile launched and landing at the same height is (T=\frac{2v_{0y}}{g}), where (v_{0y}) is the vertical component of the initial velocity of projection. Horizontal motion does not affect the time in the air. The resultant velocity and angle of projection alone are not sufficient without resolving for the vertical component.

Answer:

B. It can be calculated solely by knowing the vertical component of the velocity of projection.
