|
FALSE
|
|
|
Either A or B
|
|
|
None of the above

Explanation:
Detailed explanation-1: -Nothing accelerates a projectile horizontally, so horizontal acceleration is always zero.
Detailed explanation-2: -Horizontally, gravity only pulls an object down, it never pulls or pushes an object horizontally, therefore the horizontal acceleration of any projectile is zero.
Detailed explanation-3: -So acceleration in horizontal direction is zero and that in vertical direction is g (9.8 m/s2 vertically downwards).
Detailed explanation-4: -Horizontal acceleration is equal to 0. Vertical acceleration is equal to −g (because only gravity acts on the projectile).
