A projectile is launched at a 45 deg angle above the horizontal. Ignore air resistance. The projectile's acceleration is: zero at all points along the trajectory the same (but nonzero) at all points along the trajectory. largest at the highest point of the trajectory. lowest at a point between the high point of the trajectory and where it hits the ground.
