A projectile of mass 0.387 kg is shot from
a cannon, at height 6.4 m, as shown in the
figure, with an initial velocity vi having a
horizontal component of 7.4 m/s.
The projectile rises to a maximum height of
y above the end of the cannonâs barrel and
strikes the ground a horizontal distance x
past the end of the cannonâs barrel.
Find the magnitude of the velocity vector
when the projectile hits the ground. The
acceleration of gravity is 9.8 m/s2 .
Answer in units of m/s.
