Physics

The velocity of a projectile at launch has a horizontal component v_h and a vertical component V_V. Air resistence is negligible. When the projectile is at the hightest point of its trajectory, which of the following show the vertical and horizontal components of its velocity and the vertial component of its acceleration?

Vert. component Horz. compon Vert. a
a) V_v V_h 0
b) V_v 0 0
c) 0 V_h 0
d) 0 0 g
e) 0 V_h g

Would it be c)?

Yes.
