Which vector pair (arrow pair) correctly represents the acceleration and velocity at point P?
Who do you agree with?
Anita: “A projectile’s vx changes because of gravity, and its vy remains constant.”
Barry: “Both vx and vy are constant.”
Chris: “A projectile has no acceleration in the vertical dimension but it does accelerate horizontally.”
Dave: “A projectile has vertical acceleration and a constant horizontal velocity”
