At any instance, the projectile has a velocity, v and an acceleration a. Which one of the following drawings could NOT represent the directions of vand at any point on the trajectory? lio

Explanation / Answer

In projectile acceleration always acts in downward direction this is acceleration due to gravity (-9.8 m/s^2)

But in first figure it is shown in upward direction

So this is not possible in projectile motion
