A projectile of mass 0.318 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 7.7 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.

a)Find the vertical component of the initial
velocity at the end of the cannon’s barrel,
where the projectile begins its trajectory. The
acceleration of gravity is 9.8 m/s^2 Answer in units of m/s.

b)Determine the maximum height the projectile
achieves after leaving the end of the cannon’s
barrel.
Answer in units of m.


c)Find the magnitude of the velocity vector
when the projectile hits the ground.
Answer in units of m/s.

d)Find the magnitude of the angle (with respect
to horizontal) the projectile makes when impacting
the ground.
Answer in units of ?

e)Find the range of the projectile from the time
it leaves the barrel until it hits the ground.
Answer in units of m.
