If the cannon is 14 m above the ground, how far downrange will the projectile land?
given vi = 30 m/s, degree 30 (above the horizontal, pointing up)
What is the vi x = ? and vi y = ?
The artillery gun with a muzzle velocity of vo=150m/s is fired at the slope of the
mountain at horizontal and vertical distance of 980m and 400m. The gun was shot
at the smallest angle possible to achieve this goal.
