Two students are experimentally testing the principles of
projectile motion. Their procedure consists of taking a long-
exposure photograph of a golf ball in projectile motion in
front of a tile wall. The ball is illuminated by a strobe
(flashing) light, causing a picture of the ball to appear against
the tile each time the light flashes. The photograph of the
golf ball's projectile motion is shown. Without knowing the
width of each tile or the time between strobe light flashes,
what could the students determine from this photograph?
Select two answers.
A) That the ball's vertical motion has a constant acceleration
B) The vertical acceleration of the ball
C) That the ball's horizontal motion has a constant velocity
D) The horizontal velocity of the ball
