As a projectile thrown upward moves in its parabolic path, 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?
b)
Why? At the highest point the velocity is horizontal (vertical having decreased to zero) and acceleration is vertical (gravity)
Reply:At the highest point the velocity is horizontal. The acceleration is always vertical.
