Problem 3DQ

A projectile moves in a parabolic path without air resistance. Is there any point at which is parallel to Perpendicular to Explain.

Step-by-Step Solution:
Step 1 of 3

Solution 3DQ If acceleration has to be parallel to velocity, then the object has to be thrown vertically up or down from a height. Since the projectile is thrown at an angle with the horizontal, hence acceleration vector is never parallel to the velocity vector. At the highest point of the projectile, the velocity vector is horizontal. At this point, both the acceleration and velocity vectors are perpendicular to each other. Note that the acceleration vector for a projectile motion always acts vertically downward.
