A projectile of mass 0.377 kg is shot from
a cannon, at height 6.6 m, as shown in the
figure, with an initial velocity vi having a
horizontal component of 6.1 m/s.
The projectile rises to a maximum height of
�y above the end of the cannon’s barrel and
strikes the ground a horizontal distance �x
past the end of the cannon’s barrel. The cannon is 49 degrees above the ground.

Determine the maximum height the projectile
achieves after leaving the end of the cannon’s
barrel.

Find the magnitude of the velocity vector
when the projectile hits the ground.

Find the magnitude of the angle (with respect
to horizontal) the projectile makes when im-
pacting the ground.

Find the range of the projectile from the time
it leaves the barrel until it hits the ground.
