Question

Which statement is true for the hang time of a projectile?

A) It can be calculated solely by knowing the horizontal component of the velocity.
B) It can be calculated solely by knowing the vertical component of the velocity of projection.
C) It can be calculated solely by knowing the resultant velocity of projection.
D) It can be calculated solely by knowing the angle of projection.

Answer 1

If air resistance can be neglected, then the projectile's "hang time"
can be calculated from knowing only the vertical component of the
launch velocity. (B)
