King Arthur's knights fire a cannon from the top of the castle wall. The cannonball is fired at a speed of 48 m/s and at an angle of 29°. A cannonball that was accidentally dropped hits the moat below in 1.7 s.
(a) How far from the castle wall does the cannonball hit the ground?

Perhaps the question setter needs a history lesson? While who was King Arthur is disputed he was certainly around long before (400 years) the first cannon was made in England which was around 1540.

First start with v=u+at to find the height of the cannon.
