A projectile of mass 0.636 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 6.8 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.Find the magnitude of the velocity vector
when the projectile hits the ground. The
acceleration of gravity is 9.8 ms2. Answer in units of m/s.
