Question
Transcribed Image Text:**Projectile Motion Analysis**
A cannonball is fired from a castle with the trajectory shown in the figure. The initial velocity components are 180 m/s (horizontal) and 66 m/s (vertical). The cannonball reaches its maximum height at point H and then hits the ground target at point G.
**Question:** What is the height of point H from the ground without considering air resistance?
**Options:**
a) 222 m
b) 242 m
c) 45,000 m
d) 444 m
e) 464 m
**Diagram Explanation:**
The diagram displays a cannonball launched at a 30-degree angle from a point 20 meters above the ground. The projectile follows a parabolic trajectory, reaching its peak at point H before descending to hit the ground at point G. The trajectory indicates both horizontal and vertical components of motion, with the initial position marked on a castle.
