5. A projectile is launched with a velocity of 11 m/s at an angle of 28o above the horizontal over flat
level ground from a height of 2.0 m above ground level. How far forward does it go before hitting
the ground?

Projectile motion is easier when split into vertical and horizontal componetns.
calculate the time of flight from vertical components.
use that time to calculate the horizontal distances.
