LEARN MORE REMARKS This example emphasizes the independence of the x- and y components in projectile motion problems. QUESTION How does the magnitude of the velocity vector at impact compare with the magnitude of the initial velocity vector? O It is greater at impact. They are the same since the magnitude of the vertical component of velocity is the same at each height on the way up and on the way down. O It is greater initially O They are...
