A projectile is launched at some angle to the horizontal with some initial speed vi , and air resistance is negligible. (a) Is the projectile a freely falling body? (b) What is its acceleration in the vertical direction? (c) What is its acceleration in the horizontal direction?

(a) The projectile is a freely falling body since there is no other force than gravitation acting on it.

(b) The acceleration in vertical direction is -9.8 m/s^2, the negative sign since it is downward.

(c) The acceleration in horizontal direction is 0, since the speed in horizontal direction is constant.
