A projectile is launched at an angle of 30 to the horizontal with a speed of 30 m/s.
How does the horizontal component of its velocity 1.0 s after launch compare with its horizontal component of velocity 2.0 s after launch?

• Physics -

There is no horizontal force.
Therefore there is no change in the horizontal component of velocity.
