a,c,d are required by gravity.
b is never true, unless the projectile is sitting on a table or riding in a box in a train car
e is true only if dropped or shot downward
f is not true if shot straight up, or down. Hmm Actually, it does have horizontal motion in those two cases, the horizontal motion is zero. Zero in fact is a valid horizontal motion. So if you want to argue with your teacher, include f.
A projectile MUST____. List all that apply.
a) experience a net downward force
b) have a constant speed
c) be accelerating
d) be changing its velocity
e) be moving downward
f) have a horizontal motion in addition to a vertical motion
