Question

A projectile is thrown up with a velocity such that the X component of the initial velocity is 4m/s and Y component of the initial velocity is 3 m/s. X component of the velocity of the projectile when it hits the ground is

Answer 1

The x component of the velocity of a projectile when it hits the ground will be the same as the x component of its initial velocity. This is because the x component of the velocity of a projectile only changes due to the force of gravity, which acts in the vertical direction and does not affect the x component of the velocity.

In this case, the x component of the initial velocity of the projectile is 4 m/s, so the x component of the velocity of the projectile when it hits the ground will also be 4 m/s. Therefore, the correct answer is $\boxed{4 \text{ m/s}}$.
