(i) As a projectile thrown at an upward angle moves in its parabolic path (as shown), at what point along its path are the velocity and acceleration vectors for the projectile perpendicular to each other? (a) nowhere (b) the highest point (c) the launch point (ii) From the same choices, at what point are the velocity and acceleration vectors for the projectile parallel to each other?

the origin whose initial velocity
at the origin is v,, The vector v,t
would be the displacement of the
projectile if gravity were absent,
and the vector gt? is its vertical
displacement from a straight-line
path due to its downward gravita-
tional acceleration.
