Quantities:

  1. The projectile's velocity when it is at the highest point.
  2. The force on the projectile when it is part way up.
  3. The force on the projectile when it is at the highest point.
  4. The projectile's acceleration when it is part way down.
Choices:

A. Points straight up.
B. Points straight down.
C. Points directly to the left.
D. Points directly to the right.
