A cannonball was shot out of a tower.
The cannonball left the window at a horizontal speed of 20 m/s.
The window was at a height of 45 metres.
The ground outside of the tower was perfectly horizontal.
The cannonball's mass was 6.2 kg.
Assume gravitational acceleration of 9.8 .
What horizontal distance will the cannonball travel from the tower
before hitting the ground?
You are expected to apply the "trajectory functions" and get:
. . Vertical position: .
. . Horizontal position: .
The cannon ball hits the ground when
In that time, the cannonball travels a horizontal distance of:
